摘要: General properties of terminating bands are briefly reviewed and exemplified on the observed high-spin 158Er 156Er. The very similar features positive parity spectra N = 88 isotones Dy, Er Yb pointed out discussed. possibility to estimate B(E2)-values in from measured feeding times is explored. spin contribution different orbitals calculated as well more collective bands. One aim get some idea interaction between configurations this end we also consider a single-j shell model. limits yrast region when number valence nucleons increases usefulness these results planning future experimental studies considered.
