| Abstract: | The 242m Am isomer, a well-known candidate for photodepopulation research, has been studied in this first ever Coulomb excitation of a nearly pure (≈98%) isomer target. Thirty new states, including a new rotational band built on a K π = 6? state, have been identified. Strong K-mixing results in nearly equal populations of the K π=5? and 6? states. Newly identified states have been assigned to the K π=3? rotational band, the lowest states of which are known to decay into the ground-state band. Implications regarding K-mixing and Coulomb excitation paths to the ground state are discussed. |
