Abstract:

The mass of Ti-40 has been determined by using the isobaric multiplet mass equation method. The experimental data of the Ti-40 beta -decay were used to determine the level of the isospin analogue state of Sc-40. The ground-state mass excess and the Q(EC) value for Ti-40 were determined to be -9060 +/- 12 keV and 11466 +/- 13 keV, respectively.
