Abstract

Multiple neutron capture reactions have been studied on 193Ir targets and gamma and electron spectroscopy performed. Double neutron capture events were separated from all others and a level scheme of 195Ir deduced. Gamma-ray energies and multipolarities are tabulated. A neutron capture cross-section for the reaction 194Ir(n, γ) of 1500±290b has been determined and the neutron binding energy of 195Ir measured to be 7231.92 (6) keV. The results are discussed in terms of perturbed spin(6) symmetry and U( 6 4) supersymmetry. A σ < σmax family of levels has clearly been identified.
