| Abstract: | The availability of precisely measured fusion excitation functions have allowed the determination of experimental fusion barrier
distributions. This concept is utilised in 9Be+208Pb reaction, to reliably predict the expected complete fusion cross-sections. However, the measured cross-sections are found
to be only 68% of those predicted. The large cross-sections observed for incomplete fusion products support the interpretation
that this suppression of fusion is caused by 9Be breaking up into charged fragments before reaching the fusion barrier. |
