Abstract
The asymmetry term effects for the cross sections of (, charged particle) and () reactions at 14–15 MeV neutron incident energy have been investigated. The effects of pairing and odd-even nucleon numbers in new data and in the formula of Tel et al. [J. Phys. G. 29, 2169 (2003)] are discussed. We have determined three different parameters groups by the classification of nuclei into even-even, even-odd, and odd-even () reactions. In addition, since there are not enough experimental data available, we have considered two different parameters groups by the classification of nuclei into odd- and even- () reaction cross sections. The empirical formulas with two parameters for the evaluation of the () and () reactions cross sections are discussed in the present study.
