Recently, a complete analysis of the half-lives and branching ratios for the beta transitions between isospin T = 1/2 isospin doublets in mirror nuclei, together with detailed calculations of the radiative, isospin-symmetry breaking and nuclear structure corrections, have provided the corrected Ft-values for these mirror transitions up to A = 45.
Combining these Ft-values with results from...

We present a variational treatment of the effects of the isospin-symmetry
breaking on the superallowed Fermi $\beta$ decay of medium mass nuclei dominated
by shape coexistence and mixing allowing for a simultaneous description of the
analog as well as significant non-analog branches.
The Gamow-Teller strength distributions and the half-lives for the beta decay of
the ground state and the...

Nuclear masses are fundamental quantities in nature, reflecting the binding energy of the nucleons. In particular, experimentally determined masses of heavy nuclides provide new information on nuclear structure and test theoretical mass models in this region of the nuclear chart [1,2]. Masses of a few nobelium isotopes have been recently determined by SHIPTRAP (GSI, Darmstadt, Germany)....
