Abstract
The spectra of
8Begs fragments emitted in the interaction of 100,
200, 300 and 400 MeV 12C with 59Co, 93Nb and
197Au have
been measured and analysed. Our analysis suggests that, before breaking up,
12C may suffer a considerable energy loss which increases with increasing
incident energy. The amount of excitation energy provided to the target nucleus
in this process increases with decreasing charge of the target nucleus.
