Abstract：
The energy spectra and angular distributions of Li, Be, B particles emitted from the ¹²C+ ¹¹²Sn and ¹²C+ ¹²⁴Sn reactions at E _L=70.0MeV are measured. The angular distributions of the Li, Be, and B particles are found to be peaked around the grazing angle, without any forward peaked component.
The experimental results also showed that the cross section for emission is larger in ¹²C+ ¹¹²Sn reaction than that in ¹²C+ ¹²⁴Sn reaction, in contrast with the cross sections for Li, Be and B emissions. The indicates the effect of the neutron number of the target nucleus on the emission probability.
