Abstract
The relative importance of the various exchange terms in the single-channel resonating group method calculations of αBe elastic scattering has been investigated by calculating in each case the l=0 norm kernel ranges, the l=0 to 7 phase shifts, and the differential cross sections in the c.m. incident energies in the range 0–8 MeV. A central two-nucleon interaction commonly taken in resonating group method calculations has been used, and for a cluster model wave function has been taken. The results have been compared with one another and with the experimental data at 6.06 and 7.01 MeV. It is concluded that the resonating group method in the single-channel approximation can describe reasonably well the αBe elastic scattering at incident energies of about 6 MeV and below. The one-nucleon exchange terms between the alpha particle and are by far the most significant, followed by those involving the exchange of the whole alpha clusters.
