Abstract
Excited low-spin states in [Formula Presented] have been studied extensively with a combination of [Formula Presented]-ray spectroscopic techniques. We have performed photon scattering experiments, [Formula Presented] coincidence measurements following the [Formula Presented] decay of [Formula Presented] in-beam [Formula Presented] coincidence studies with the reaction [Formula Presented] and [Formula Presented] measurements. These experiments yielded detailed information about the low-spin level scheme of [Formula Presented] From measured lifetimes, branching ratios, and multipole mixing ratios, many absolute transition strengths were determined. These data permitted the interpretation of several low-spin states in terms of collective excitations, that are not fully symmetric with respect to the proton-neutron degree of freedom, the so-called mixed-symmetry (MS) states: The one-phonon [Formula Presented] MS state and three members of an expected multiplet of two-phonon MS states were identified from absolute [Formula Presented] and [Formula Presented] transition strengths. The data also enable us to identify several proton-neutron-symmetric multiphonon states.
