Beta-decay half-lives calculated on the gross theory
TLDR

Half-life of short-lived neutron-excess nuclei that participate in the r -process
TL;DR: In this paper, a quasi-classic model of a strength function based on finite Fermi systems is used to predict β-decay periods for neutron-excess nuclei.

TL;DR: In this paper, the LISE spectrometer was used for the separation of a projectile-like fragment from the interaction of a 60 MeV/n40Ar beam with a Be target, from which a half-life of (2.25±0.15)s was determined.
The Astrophysical r-Process From to Present
TL;DR: In this article, the authors focus on progress in the r-process nucleosynthesis, with emphasis on the most recent developments in nuclear physics, and present considerably improved r- abundance calculations, which were for the first time based on a modern, internally consistent nucleartheory input.

Nuclear masses and deformations
W.D. Myers,W.J. Swiatecki +1 more
TL;DR: In this article, a semi-empirical theory of nuclear masses and deformations is presented, where the potential energy of a nucleus, considered as a function of N, Z and the nuclear shape, is given by the liquid-drop model, modified by a shell correction.

On the Fermi Theory of β -Radioactivity. II. The "Forbidden" Spectra
E. J. Konopinski,G. E. Uhlenbeck +1 more
TL;DR: In this article, Fermi's original "polar vector" form of the theory was extended to first and second forbidden transitions for arbitrarily charged nuclei and the final results were given in the form of a "correction factor" $C, by which the allowed distribution must be multiplied to give a forbidden spectrum.

Conserved Current Hypothesis and the Beta Decay of RaE
TL;DR: In this paper, it is shown that the conserved current theory is consistent with Bi/sup 210/ beta decay by comparing theoretical predictions with experimental data obtained from electron polarization and spectrum measurements.

Gross Theory of Nuclear β-Decay
Kohji Takahashi,Masami Yamada +1 more
TL;DR: In this paper, a theory for the gross properties of the nuclear a-decay is developed, where summations over final states are replaced by integrations, and the average of the squared absolute value of a nuclear matrix element times the final level density is investigated instead of individual matrix elements.

Strength-function phenomena in electron-capture beta decay
TL;DR: In this article, the authors derived approximate beta strength functions from measurements of the electroncapture beta feed to the high-lying excited states in about 40 neutron-deficient nuclei.
