Title: β -decay Q values among the A = 50 Ti-V-Cr isobaric triplet and atomic masses of Ti 46 , 47 , 49 , 50 , V 50 , 51 , and Cr 50 , 52 54

Abstract

This manuscript describes a measurement of the Q value for the highly forbidden beta-decays of 50V and the double electron capture decay of 50Cr. The Q value corresponds to the total energy released during the decay and is equivalent to the mass difference between parent and daughter atoms. This mass difference was measured using high precision Penning trap mass spectrometry with the Low Energy Beam and Ion Trap facility at the National Superconducting Cyclotron Laboratory. The Q value enters into theoretical calculations of the half-life and beta-decay spectrum for the decay, so improves these calculations. In addition the Q value corresponds to the end point energy of the beta-decay spectrum, which has been precisely measured for several highly-forbidden decays using modern low background detector techniques. Hence, our Q value measurements provide a test of systematics for these detectors. In addition, we have measured the absolute atomic masses of 46,47,49,50Ti, 50,51V, and 50,52-52Cr, providing improvements in precision by factors of up to 3. These atomic masses help to strengthen global evaluations of all atomic mass data, such as the Atomic Mass Evaluation.
