A new empirical formula for cross-sections of (n,nα) reactions

Studies on the cross-sections of (n,n alpha) reactions which are energetically possible, about 14 MeV neutrons are quite scarce. In this paper, the cross-sections of (n,n alpha) nuclear reactions at E-n =14-15 MeV are analyzed by using a new empirical formula based on the statistical theory. We show that neutron cross-sections are closely related to the Q-value of nuclear reaction, in particular for (n,n alpha) channels. Results obtained with this empirical formula show good agreement with the available measured cross-section values. We hope that the estimations on the cross-sections using the present formalism may be helpful in future studies in this field.
