Measurement of absolute intensities of some prompt γ-lines from the 91Zr, 143Nd, 177Hf and 116,118–120,122,124Sn(n,γ) reactions and isomeric cross-sections of 123m,125mSn by in-beam γ-spectroscopy method

The previously unknown absolute intensities of 28 prompt γ-rays from the thermal neutron capture in 91Zr, 143Nd, 177Hf and 116,118–120,122,124Sn were measured by an in-beam γ-spectroscopy method at the WWR-M reactor (PNPI, Gatchina). Cross sections of the production of isomers 123m,125mSn were also measured.
