Optimal-monoenergetic representation of results of photonuclear experiments in $\gamma$-bremsstrahlung

To study the possibility of obtaining an optimal-monoenergetic representation of the cross section of a photonuclear reaction if one knows the experimental reaction yield measured with the help of a $\gamma$-bremsstrahlung beam the reduction method is used. The specially introduced generalized parameters of the cross sections of the reactions $^{34}$S$(\gamma,sn)$ and $^{52}$Cr$(\gamma,n)^{51}$Cr obtained earlier are studied as functions of actually attained energy resolutions. It is found that the optimal-monoenergetic representations of the reaction cross sections attained at resolutions amounting to 0.25 and 0.20 MeV, respectively, differ substantially from those obtained in both experiments.
