Angular momentum distributions and delayed feeding in (d, 3n) reactions to deformed nuclei

The relative intensities of ground-state rotational band transitions in 158 Dy, 164 Er, 168 Yb, 174 Hf and 180 W have been studied with particular emphasis on the identification of delayed feeding from high- K isomers. The results are interpreted in terms of a simple formulation of the K -conservation model which is introduced to explain the discrepancy between the observed intensity distributions and those expected from the statistical model.
