Reaction cross sections of intermediate energy 3He-particles on targets from 9Be to 208Pb

Abstract Reaction cross sections for 3 He-particles have been measured for 9 Be, 12 C, 16 O, 28 Si, 40 Ca, 58,60 Ni, 112,116,118,120,124 Sn, and 208 Pb at 96, 138 and 167 MeV. The results are compared with predictions from optical model calculations using phenomenological and global optical potentials. The behaviour of the wavefunctions and of the contributions to the reaction cross sections from different regions in the nucleus is investigated. Comparisons are also made with results for α -particles obtained in the same energy region.
