Neutron resonance parameters of 177Hf

The capture gamma-ray multiplicity in the reaction 177Hf + n was measured by a 16-section NaJ(Tl) scintillation detector in a time-of-flight neutron spectroscopy experiment. Between 300 and 700 eV new experimental data were obtained on the spins of the resonances, making use of the gamma-cascade multiplicity method. The possibility of this method for identification of strongly overlapped resonances with different spin is shown. In the energy interval from 0 to 700 eV, the strength functions obtained as S0 (2.70-0.29=0.36)· 10-4 for J = 4 and S0 (2.58-0.34+0.47)· 10-4 for J = 3, were found to be continued within the errors. 13 refs., 4 figs., 2 tabs
