STUDY OF THE PHOTONUCLEAR REACTION CROSS-SECTION 165Но(γ,n)164m,gНо ON THE M-30 MICROTRON AT THE ENERGY OF 10…18 MeV

The study results of the isomeric yield ratios in the reaction 165Но(γ,n) 164m,g Но in the region of giant dipole resonance (GDR) energies of 10…18 MeV are presented. The experimental values of the isomeric yield ratios as a function of the maximum energy of the gamma quanta of the braking spectrum are presented. The obtained data are used to get the excitation cross-section of the 164mHo isomeric nucleus state using the inverse matrix method with a step of ∆Е = 0.5 MeV. It is shown that this cross section has a two-humped shape with a maximum of σm=100.93 mb at 12.5 MeV and σm=108.79 mb at 14.5 MeV. The results of comparing experimental and theoretical data obtained with different models of the TALYS-1.6 software package are discussed.
