    Investigation of the pairing effect using newly evaluated empirical studies for 14-15 MeV neutron reaction cross sections
    (American Physical Soc, 2007) Tel, E.; Aydin, A.; Tanir, G.
    The asymmetry term effects for the cross sections of (n, charged particle) and (n,2n) 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 [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 (n,d) 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-A and even-A (n,t) reaction cross sections. The empirical formulas with two parameters for the evaluation of the (n,d) and (n,t) reactions cross sections are discussed in the present study.

    A new empirical formula for 14-15 MeV neutron-induced (n, p) reaction cross sections
    (Iop Publishing Ltd, 2003) Tel, E.; Sarer, B.; Okuducu, S.; Aydin, A.; Tanir, G.
    In this study, we have suggested a new empirical formula to reproduce the cross sections of the (n, p) reactions at 14-15 MeV for the neutron incident energy. This formula obtained using the asymmetry parameters represents a modification to the original formula of Levkovskii. The resulting modified formulae yielded cross sections, representing smaller chi(2) deviations from experimental values, and values much closer to unity as compared with those calculated using Levkovskii's original formula. The results obtained have been discussed and compared with the existing formulae, and found to be well in agreement, when used to correlate the available experimental sigma(n, p) data of different nuclei.
