Dh. Smalley et al., EVIDENCE FOR A ROTATIONAL ALIGNMENT IN A HIGH-K BAND IN YB-167, Journal of physics. G, Nuclear and particle physics, 22(10), 1996, pp. 1411-1420
gamma-rays depopulating high-spin states in Yb-167 have been detected
using the EUROGAM phase-1 array. A crossing which is possibly observed
at a rotational frequency of (h) over bar omega similar or equal to 0
.31 MeV in a h(11/2) quasi-neutron band is interpreted as being due to
the alignment of a pair of i(13/2) neutrons.
