Measuring the half-life of n-rich Rb-100 with the TITAN MR-TOF-MS
27TH INTERNATIONAL NUCLEAR PHYSICS CONFERENCE (INPC2019)(2020)
Abstract
Multiple-reflection time-of-flight mass spectrometers (MR-TOF-MS) have been demonstrated to have a mass resolving power in the range of few hundreds of thousand. The TITAN MR-TOF-MS has been used to separate isobaric impurities and measure masses of many rare isotopes. Recently we have measured the mass and half-lives of neutron-rich Rubidium isotopes with the MR-TOF-MS. This technique is capable of measuring the half-life of rare isotopes in the range of few tens of millisecond. In this proceeding, we present the measurement of half-life of Rb-100 that was found to be 50 +/- 5 ms, in good agreement with literature value of 48 +/- 3 ms.
