Negative-parity states near the yrast line in {sup 144}Nd
- Department of Physics, Florida State University, Tallahassee, Florida 32306-3016 (United States)
The near-yrast spectrum of the {ital N}=84 isotope {sup 144}Nd has been studied using the {sup 130}Te({sup 18}O,4{ital n}) reaction at a lab energy of 85 MeV and the techniques of {gamma}-ray spectroscopy. Sixteen new states and 23 new {gamma} rays were placed in the level scheme. Most of the yrast and near-yrast negative-parity states have been interpreted in terms of empirical shell-model configurations. However, the interpretation of a sequence of states from {ital J}=17--24 in terms of the {ital h}{sub 11/2}{sup 3}{ital g}{sub 7/2}{sup {minus}1}{ital d}{sub 5/2}{sup {minus}6} proton configuration is problematic because the observed energies cannot be satisfactorily reproduced with empirical shell-model calculations.
