A bibliography of low energy electron collision
cross section data is presented. Only references
which report original measurements or calculations
of electron collision cross sections are included.
The cross section data for each process are listed
by atomic species in order of their atomic number.
The data for molecules are listed in arbitrary
order.

INTRODUCTION

The Joint Institute for Laboratory Astrophysics (JILA) maintains an Information Center for collecting reports which contain information of interest to plasma physicists and astrophysicists. Because of the availability of information from other data centers, our scope is confined to low energy atomic collision data. Our obligation to the National Standard Reference Data System requires that we make available to the general scientific and technical community critically evaluated data for electron and photon collisions with atoms and simple molecules.

This Bibliography has been issued previously in report form (JILA Reports
#4 and #34, and JILA Information Center Report #2). All previous
versions of this bibliography, and this one, have included all of the
bibliographic material in our files at the time of publication. The
current literature for this publication was searched through October
1966. Because we rely upon the abstracting journals to obtain references
from sources which do not in general contain information of interest,
there may be some material from late 1966 which is not included in this
bibliography. The current scientific literature will be searched for
this material on a continuing basis and all future bibliographic material
will be issued in conjunction with the publication of critically
evaluated data.

This research was supported in part by the Advanced Research Projects
Agency (Project DEFENDER), monitored by the U. S. Army Research
Office-Durham, under Contract DA-31-124-ARO-D-139, and in part by the
National Bureau of Standards through the National Standard Reference
Data Program.

Electron Scattering Cross Section Bibliography

The criterion used in choosing the references for this bibliography is that the publication contain original measurements or calculations of electron cross sections in the energy range 0 to 10 KeV for specific atomic or molecular targets. The upper limit on the energy was not used as an absolute limit but indicates the order of magnitude of interest. This means that one should not expect to find electron collision cross sections in the range of 50 KeV and above.

Papers containing the following quantities, which are not explicitly cross sections, have also been collected:

The reason for including these quantities is that under the proper conditions cross sections have been or can be simply derived from them. Published manuscripts, theses, reports given at meetings, and company or agency reports which have been printed and circulated are included in the bibliography. However, reference is not made to material that is unavailable either through library facilities or government document centers. (No classified material is included.)

There is a tendency for authors to publish material which is identical to that which they have reported on at a meeting (which is printed and circulated) and also issued as a company or agency report. In some cases it is possible to verify that this is so and in those cases only one reference (the formal publication if there is one) is kept in our bibliography. In most cases it is not possible to make such a precise distinction among such documents, since only some of the material may have been made available before. Because of this, there may be cases, of duplication in the sense that there may be more than one reference to the same original data. We have tried to keep this to a minimum consistent with our aim of collecting all published data.

Inclusion of a reference in this bibliography does not imply a value judgment about the accuracy of the information. We only assert that this reference reports a measured or calculated electron collision cross section (or the equivalent as described previously). The question of the accuracy of the data is to be covered in separate published critical reviews [see, for example, Reviews of Modern Physics, 38, 1, (1966)].

Description of the Bibliography Format

The Electron Cross Section Bibliography is divided into three main sections. The first section describes the data which are in the references included in the bibliography. The data are categorized by a

hierarchy of descriptors in the following order:

Process (e.g., elastic scattering, electronic excitation, etc.)
Experimental or Theoretical

Normalized or Relative

(The data are considered normalized if given in
absolute units.)

Atomic or Molecular Species including the degree of
ionization of the species.

(A negative ion is indicated by a minus sign; neutral
unexcited species by a blank; neutral excited species
by a star; and a positive ion by a number indicating
the degree of positive ionization. All of these
symbols follow the atomic species, which are listed
in ascending order of nuclear charge, Z. Molecular
species are listed in arbitrary order.)

The references in which the data described are found.
The references are identified by an arbitrary file
number, the first author and the year of publication
(e.g., 63 implies 1963).

The following comments about categories (see Contents) are necessary in val order to use the bibliography properly. Category ELASTIC SCATTERING, for theoretical papers, includes all references to elastic scattering cross section computations except differential elastic scattering cross section references, which are given in a separate category. In the case of exper1imental papers only those references in which cross section measurements were reported with energy discrimination for the scattered electrons are Sincluded under ELASTIC SCATTERING.

Category TOTAL SCATTERING includes theoretical papers which give a total cross section which is the sum of elastic and inelastic cross sections. It also includes any references to experimentally determined cross sections in which the experiment does not distinguish between elastically and inelastically scattered electrons even if the experiment is carried out in an energy range in which only elastic scattering is expected.

The second section lists the title, authors and complete reference for the paper cited. These are ordered by their "file" number.

The abbreviations for journal titles are taken from Chemical Abstracts or if not abstracted there, from Science Abstracts, Section A: Physics Abstracts.

The third section consists of an alphabetical author index. After each name is a list of the "file" numbers of articles authored or co-authored to be found in the bibliographic section.
