Exp 14 N + exp 10 B Fusion and Elastic Scattering Cross Section Measurements Near the Interaction Barrier.

摘要

The exp 14 N + exp 10 B fusion reactions were studied at c.m. energies between 2.9 and 7.5 MeV by measuring the yields of gamma -rays from the residual nuclei formed by particle evaporation from the compound system. Cross sections for formation of the evaporation residues exp 16 O, exp 19 F, exp 19 Ne, exp 20 Ne, exp 21 Ne, exp 22 Ne, exp 22 Na, exp 23 Na and exp 23 Mg, as well as the total cross section, were deduced from these yields with the aid of statistical model calculations. exp 14 N + exp 10 B elastic scattering differential cross sections were measured from 4.3 to 9.1 MeV at THETA 74.4 degrees, and from 3.3 to 8.3 MeV at THETA = 90.0 degrees. The elastic scattering cross sections were analyzed within the framework of the incoming-wave boundary condition (IWBC) model. The fusion cross sections calculated for the real ion-ion potential deduced from the IWBC model fit to the elastic scattering are in good agreement with the measured values.
