Penning Trap Mass Spectrometry of Exotic Nuclei
Argonne Physics Division Seminar - 5 Apr 2010

Manipulation of radioactive isotopes with ion traps has opened new opportunities in nuclear spectrometry. The applications employed so far include high-precision mass measurements as well as many other applications where high sensitivity and purity is obtained through ion manipulation in Penning and Paul traps. In my talk I will discuss some recent experiments and mass measurements related to nuclear structure studies near the magic neutron numbers 50 and 82 [1], studies of rapid proton capture process near 100Sn [2], precision measurements of nuclear beta decays for electroweak physics [3] and accurate Q-value measurements for double beta decay and electron capture experiments [4].
