A new experimental investigation of the level scheme of the N=Z+1 nucleus 81Zr is reported. An additional band assigned to the [431]1∕2+ orbital has been observed and the known [422]5∕2+ and [301]3∕2− bands have been extended to higher spins. The behavior of these bands is compared to that of the bands in the isotonic nucleus 79Sr, for which some new experimental data are presented. Comparison is also made to the even-even N=Z and N=Z+2 neighbors. The band structures are discussed in the framework of the projected shell model.

Abstract
A new experimental investigation of the level scheme of the N=Z+1 nucleus 81Zr is reported. An additional band assigned to the [431]1∕2+ orbital has been observed and the known [422]5∕2+ and [301]3∕2− bands have been extended to higher spins. The behavior of these bands is compared to that of the bands in the isotonic nucleus 79Sr, for which some new experimental data are presented. Comparison is also made to the even-even N=Z and N=Z+2 neighbors. The band structures are discussed in the framework of the projected shell model.File in questo prodotto:
