Precise Determination of 40Ti Mass by Measuring the 40Sc Isospin Analog State
Abstract： The mass of 40Ti has been determined by using the isobaric multiplet mass equation method. The experimental data of 40Ti β-decay were used to determine the level of the isospin analog state of 40Sc. The ground-state mass excess and the QEC value for 40Ti were determined to be -9060±12keV and 11466±13keV, respectively.
