Abstract

Lifetime measurements of some rotational levels have been carried out by observing the decay of the excited nuclei along the recoil path following Coulomb excitation with back-scattered oxygen ions. Mean lives were determined for levels in ¹⁶¹Dy, ¹⁷¹Yb, ¹⁶⁷Er, ¹⁸³W and ¹⁹⁰Os. In ¹⁶¹Dy, the parameter g_R determined from the mean life g_R = 0.14 ± 0.02, is somewhat larger than the value calculated in a pair correlation theory. The abrupt change predicted by this theory in the g_R values from ¹⁶¹Dy to ¹⁶³Dy is definitely established.
