ARC spectra from the reaction 115In(n, γ) and temperature dependence of the width of the giant magnetic resonance

The resonance-averaged spectra of primary γ transitions in the reaction 115In(n, γ) are analyzed at the average neutron energies of En=1.9, 24.3, and 134 keV. The temperature dependence of the width of the giant magnetic resonance is found by parametrizing the observed intensities of M1 transitions.
