High-spin levels in the odd-odd nucleus142Eu


High-spin states up to I=22hstrok have been observed for the first time in the odd-odd nucleus142Eu above the 8\u2013 beta+ -decaying isomer. A new isomer of mean life taum=9.0\ub1 0.6 ns and Jpgr=8+ has been identified. The low energy part of the level scheme is interpreted in terms of single-particle excitations in the 2d5/2 and h11/2 orbitals and of the N=80 core excitations
