| Popis: |
Peripheral interactions of the 22 Ne + 93 Nb system at 30 A· MeV incident energy have been investigated using the forward 48 CsI scintillators of the AMPHORA multidetector array for the detection of light charged particles at forward angles. In addition fragments have been identified near the grazing angle in 4 Si-CsI telescopes. It is found that the transfer probability remains large at this intermediate energy. The stripping of one or two nucleons from the projectile to the target and the pick-up of one nucleon have been clearly observed. Binary quasi-projectile break-up events involving emission of one α are dominant. Dissociation of the projectile into up to five products has also been observed. The production of fragments is deduced to result mainly from sequential decay of the primary fragments rather than from a direct break-up process. The yields of fragments, except for the lightest ones, have been reproduced in the framework of a random-walk model. |
