Notes:
Abstract High-spin states in154Er have been populated by bombarding147Sm and148Sm with12C particles. Excitation functions, lifetimes, angular distributions andγ-γ coincidences were measured. AT 1/2=35ns isomeric state atE x∼3 MeV has been found and is interpreted as a two-quasi-particle state with aligned angular momenta. A cascade of intense individual lines from states with spin up to at least 26 (excitation energy up to 8.543 MeV) was found to feed the isomeric state. The level sequence above this yrast trap exhibits an irregular pattern which cannot be easily interpreted in terms of collective modes.
