Tiivistelmä

A charge plunger device has been commissioned based on the DPUNS plunger (Taylor et al., 2013) using the in-flight mass separator MARA at the University of Jyväskylä. The 152(32,4n)180 reaction was used to populate excited states in 180. A lifetime measurement of the state was performed by applying the charge plunger technique, which relies on the detection of the charge state-distribution of recoils rather than the detection of the emitted rays. This state was a good candidate to test the charge plunger technique as it has a known lifetime and depopulates through a converted transition that competes strongly with -ray emission. The lifetime of the state was measured to be , which is consistent with previously reported lifetimes that relied on the standard -ray techniques. The charge plunger technique is a complementary approach to lifetime measurements of excited states that depopulate through both -ray emission and internal conversion. In cases where it is not possible to detect Doppler-shifted rays, for example, in heavy nuclei where internal conversion dominates, it may well be the only feasible lifetime analysis approach.
