Abstract
The parameters of the 1.100-ev and the 2.39-ev resonances in hafnium have been determined from total cross section measurements using the Brookhaven crystal spectrometer. The methods of analysis used take into account the Doppler broadening and the finite resolution of the instrument. The radiation widths of the 1.100-ev and the 2.39-ev resonances are 0.067 ev and 0.060 ev, respectively. The remaining one-level parameters for each resonance are presented.
