Precision Mass Measurements of Radioactive Isotopes

Abstract: Presently, Penning trap mass spectroscopy provides the highest precision for atomic measurements. Relative precision of \delta m/m = 10^{-10} is achievable. Unfortunately, the technique is not well suited for use with radioactive ions produced via fusion-evaporation reactions or inflight fragmentation -- techniques capable of producing the most exotic isotopes. To bridge the gap, so-called gas stopping techniques have been developed. I will discuss the present and future capabilities of gas stopping systems and introduce a new high-precision atomic mass measurement technique under development at RIKEN.

Bio: Peter Schury is a lecturer at Tsukuba University in Ibaraki, Japan. He is presently working on implementing an advanced multi-turn time-of-flight mass spectrometer at RIKEN. In conjunction with an advanced gas stopper, the device will allow for precise mass measurement of very short-lived (>1ms) species very far from stability.

RIKEN offers a premier nuclear science facility on the global stage. With the new RIBF facility and
the BigRIPS fragment separator, RIKEN provides access to many rare isotopes with unsurpassed
intensity.
