Izomer ratios of /sup 184m,g/Re in (. alpha. n) and (. gamma. n) reactions

Investigations of /sup 184m,g/Re isomer ratios in ({alpha}n) and ({gamma}n) reactions at high energies and with minimum number of emerging particles are carried out. Isomer ratios were determined by activation method. Calculations of isomer ratios in cascade-evaporation model with the level density from Fermi-gas model with inverse shift are carried out. It is shown that /sup 184/Re inertia moment in the 0-4 MeV excitation energy range is almost the same as of solid one.
