The level structure of 104Rh deduced from the 103Rh(n,γ)104Rh reaction

A sensitive, high resolution study of the 103Rh(n,γ)104Rh reaction has revealed the presence of 516 transitions in the energy range 3,700 to 7,000 keV. These results have been used to interpret the reaction in terms of a statistical model in which a constant temperature level density is assumed. Previous work which revealed a much simpler level structure is quantitatively explained in terms of resolution and sensitivity. The average reduced radiative width is significantly lower than that reported for nuclides in the A = 100 mass region and the width shows an indication of an energy dependence somewhat greater than E3sub(γ). The neutron separation energy of the reaction is found to be 6.999.0 +- 0.1 keV. (orig.)
