Nuclear weak-interaction processes in stars
TL;DR: In this paper, a review of recent advances in nuclear structure modeling has led to improved descriptions of astrophysically important weak-interaction processes and their applications to hydrostatic solar and stellar burning, to slow and rapid neutron capture processes, to neutrino nucleosynthesis, and to explosive hydrogen burning.

High precision analytical description of the allowed β spectrum shape
TL;DR: In this paper, a fully analytical description of the allowed β spectrum shape is given in view of ongoing and planned measurements, which forms an invaluable tool in the search for physics beyond the standard electroweak model and weak magnetism recoil term.

First-forbidden transitions in the reactor anomaly
TL;DR: In this paper, the dominant forbidden transitions in reactor antineutrino spectra above 4 MeV were investigated using the nuclear shell model and the shape factor with the highest fidelity was calculated.

DEVIATION FROM THE /xi/ APPROXIMATION IN FIRST FORBIDDEN $beta$ DECAY
TL;DR: In this article, it was shown that the failure of the approximation in which only the first nonvanishing term is kept in the expansion in descending powers of the Coulomb energy factor is due to either cancellation or selection rule effect.
Journal ArticleDOI
Beta decay theory using exact electron radial wave functions
TL;DR: In this article, a modified formulation of the theory of beta decay is presented in which exact electron radial wave functions for an extended nuclear charge distribution are used for accurate application as well as for a qualitative demonstration of the features of the beta decay.

Use of conserved vector current theory in first forbidden β-decay
J. Damgaard,A. Winter +1 more
TL;DR: In this paper, the first forbidden β-decay matrix elements (α and ǫ) are shown to have been connected by a formula connecting the first two elements, and the use of critical use of the formula is shown to be unjustified.

First-Forbidden Beta Decay
TL;DR: In the last few years study of the laws of β decay has been the object of many experimental and theoretical investigations as mentioned in this paper, and the form of the nuclear β-decay interaction is now well-established.
