The R-process and nucleochronology
TL;DR: A review of the basic physics underlying the r-process, the operation of the mechanisms for rprocess nucleosynthesis, the possible astrophysical sites, their time evolution in galactic evolution models, and the inferred ages of the Galaxy can be found in this article.
Journal ArticleDOI
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.

New calculations of gross β -decay properties for astrophysical applications: Speeding-up the classical r process
TL;DR: In this article, the authors combine calculations within the quasiparticle (QP) random-phase approximation for the Gamow-Teller (GT) part with an empirical spreading of the QP strength and the gross theory for the first-forbidden part of the GT decay.

Beta-decay rates of highly ionized heavy atoms in stellar interiors
K. Takahashi,K. Yokoi +1 more
TL;DR: In this paper, the Saha equation corrected for the continuum depression within a finite-temperature Thomas-Fermi model was used to determine the degree of ionization for heavy nuclides.
Journal ArticleDOI
Presupernova Evolution with Improved Rates for Weak Interactions
TL;DR: In this article, the effects of modern shell-model calculations of weak-interaction rates for nuclei in the mass range A = 45-65 have resulted in substantial revisions to the hitherto standard set of Fuller, Fowler, & Newman (FFN).

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.
