Cross-sections of reactions ( gamma , gamma ')"m and ( gamma , n)"m on nuclei with a=70-140 in field of energies 4-20 mev

The paper is concerned with isomeric states of the atomic nuclei. The aim is to study the isomeric state excitation of atomic nuclei in reactions ( gamma , gamma ') and ( gamma , n). First the isomeric relation evaluations of cross-sections in reaction ( gamma , n) on base of the half-direct decay widths of the gigantic dipole resonance with use of spectroscopic level factors from neutron catch have been obtained. The measurement methods have been developed in the stopping beam of microtron M-30 for Uzhgorod Branch of Nuclear Investigation Institute, Ukrainian Academy of Sciences. First the cross-sections of exciting isomeric states for nuclei of "4"4Sc, "7"7Se, "7"9Br, "8"7Sr, "8"9Zr, "9"1Mo, "1"1"1Cd, "1"3"7Ba have been produced in the reactions ( gamma , gamma ') and ( gamma , n).
