Abstract

With a summation-free β ⁺ -endpoint spectrometer the β ⁺ -decay energies of ¹⁰⁴ Sn, ¹⁴⁷ Tb, ^{148, 149} Dy, ¹⁴⁹ Ho, ¹⁵⁰ Er, and ¹⁵¹ Tm were remeasured with improved accuracy. Combined with known proton and alpha decay energies, the resulting Q _EC values lead to atomic masses of very neutron-deficient isotopes including nuclei beyond the proton drip-line such as ¹⁰⁹ I and ¹¹³ Cs. Furthermore, the Gamow-Teller β-strength of the even-even nuclei ¹⁰⁴ Sn, ¹⁴⁸ Dy, and ¹⁵⁰ Er is reevaluated with reduced uncertainty.
