Structure of high-lying levels populated in the Y-96 -> Zr-96 beta decay
The nature of levels of Zr below the -decay value of Y has been investigated in high-resolution -ray spectroscopy following the decay as well as in a campaign of inelastic photon scattering experiments. Branching ratios extracted from decay allow the absolute excitation strength to be determined for levels populated in both reactions. The combined data represents a comprehensive approach to the wavefunction of levels below the value, which are investigated in the theoretical approach of the Quasiparticle Phonon Model. This study clarifies the nuclear structure properties associated with the enhanced population of high-lying levels in the Y decay, one of the three most important contributors to the high-energy reactor antineutrino spectrum
