Q(EC) values of the superallowed beta emitters (10)C, (34)Ar, (38)Ca, and (46)V
Abstract
The Q(EC) values of the superallowed beta(+) emitters (10)C, (34)Ar, (38)Ca, and (46)V have been measured with the JYFLTRAP Penning-trap mass spectrometer to be 3648.12(8), 6061.83(8), 6612.12(7), and 7052.44(10) keV, respectively. All four values are substantially improved in precision over previous results. Of the well-known superallowed emitters, only (14)O has yet to have had its Q(EC) value measured with a Penning trap.
