The intensities of γ-rays from the decay of 196m2Au

Abstract The intensities of γ -rays from the 196m2 Au decay adopted in 1998 and 2007 ENSDF evaluations differ up to 20%. Gold samples were irradiated in intensive neutron fluxes with energies up to 35 MeV to produce the isotopes 196 Au in all isomeric states. The intensities of gammas from the radioactive decay of the isomer 196m2 Au were measured by means of the nuclear γ -ray spectrometry (HPGe detectors) and compared to the existing adopted data.
