Abstract

Single-γ, γγ-coincidence, and γ-ray angular distribution spectra of the 106Cd(p, )106In reaction were measured with Ge(HP), Ge(Li), and Ge(LEPS) detectors at various bombarding proton energies between 8 and 11 MeV. Altogether 141 (among them 117 new) transitions have been assigned to 106In. The conversion electrons were studied with an intermediate-image magnetic spectrometer plus Si(Li) detector, as well as with a superconducting magnetic lens combined with a Si(Li) detector. Internal conversion coefficients have been determined for 22 transitions. A more complete level scheme of 106In, containing 49 levels below 1650 keV excitation energy, has been proposed. On the basis of the internal conversion coefficients of transitions, Hauser-Feshbach analysis of (p, n) reaction cross sections, γ-ray angular distributions and other arguments, spin and parity values have been deduced. The energy splittings of pn multiplets have been compared with the predictions of the parabolic rule. The energy levels, wave functions, electromagnetic moments, as well as reduced M1 and E2 transition probabilities were calculated in the framework of the interacting boson-fermion-fermion/odd-odd truncated quadrupole phonon model (IBFFM/OTQM), and resonably good agreement was obtained with experimental data.
