An evaluation of the alpha-cluster formation factor in (n, α) reactions

In this work we suggest some methods based on the statistical and knock-on models, for evaluation of the α -clustering factor or α -clustering probability in ( n, α ) reactions induced by slow and fast neutrons. The main purpose of this study is to compare the values of the α -clustering factors obtained by the compound and direct mechanisms for the same nuclear reactions. Also, our results are compared with values estimated by other authors.
