Calculation the Cross Sections of P10^B(n,p)P10^Be Reaction by Using the Reciprocity Theory for the First Excited State

In this study light elements P^10PB ,P ^10PBe for P^10PB(n,p)P^10PBe reaction as well as proton energy from 0.987 MeV to 2.028 MeV with threshold energy (1.04MeV) are used according to the available data of reaction cross sections. The more recent cross sections data of P^10PBe (p,n)P^10PB reaction is reproduced in fin steps in the specified energy range , as well as cross section (p,n) values were derived from the published data of (n,p) as a function of energy in the same fine energy steps by using the reciprocity theory of principle inverse reaction . This calculation involves only the first excited state of P ^10PB ,P ^10PBe in the reactions P^10PBe(p,n)P^10PB and P^10PB(n,p)P^10PBe.
