**momentum transfer**is d≈a1 . We can then estimate the " healing " length , L , of the shadow : L 1 , L2ka2 ; 2ka2 for a = 1 fm , k = 10 GeV we obtain 2ka2 = 2X10 GeVX25 GeV - 2 = 100 fm . Note that ( 3.1 ) gives , as r → ∞ , ( compare ... Page 27

**momentum transfer**( 42≈2 GeV2 ) . What is the cause ? Perhaps some relativistic effects ? There is no good answer ...**momentum transfers**( A2 / M2 ~ 1 ) this is probably not a good approximation . Take the deuteron example . In the ... Page 35

...

**momentum transfer**can also be neglected . So , in the limit p → 0 all the states taking part in diffractive production processes can be considered degenerate and the longitudinal**momentum transfer**neglected . As was said , however ... Page 43
