Abstract

States in [Formula Presented] have been observed with the [Formula Presented] reaction using both spallation and monoenergetic accelerator-produced neutrons. A scheme comprised of 81 levels and 157 transitions was constructed concentrating on levels below 5.6 MeV in excitation energy. Spins have been determined by considering data from all experimental studies performed for [Formula Presented] Lifetimes have been deduced using the Doppler-shift attenuation method for many of the states, and transition rates have been obtained. A spherical shell-model interpretation in terms of particle-hole excitations assuming a [Formula Presented] closed core is given. In some cases, enhancements in [Formula Presented] and [Formula Presented] values are observed that cannot be explained by assuming simple particle-hole excitations. Shell-model calculations using an extended [Formula Presented]-shell-model space reproduce the spectrum of excited states very well, and the gross features of the [Formula Presented] and [Formula Presented] transition rates. Transition rates for individual levels show discrepancies between calculations and experimental values.
