Second-generation microscopic predictions of beta-decay half-lives of neutron-rich nuclei
TL;DR: In this paper, a second-generation microscopic calculation using the proton-neutron quasiparticle random-phase approximation (QRPA) with a Gamow-Teller residual interaction is presented.

Cold fusion in symmetric 90Zr-induced reactions
J. G. Keller,K.-H. Schmidt,F. P. Hessberger,G. Münzenberg,W. Reisdorf,H.-G. Clerc,C. C. Sahm +6 more
TL;DR: In this article, the α-spectroscopic information was obtained for neutron-defi- cient isotopes between Ir and Pb using the measured cross-sections of the compound nuclei.

Beta-decay half-lives of neutron-rich nuclei
TL;DR: In this article, a microscopic theory for nuclei with 6 ε Z ⩽ 114 between the line of beta-stability and the neutron drip line was proposed. And the accuracy of the predictions was considerably improved over that of an earlier prediction based on a "gross theory" of beta decay.

Computational methods for nucleosynthesis and nuclear energy generation
TL;DR: In this paper, a review on the two principle methods used to evolve nuclear abundances within astrophysical simulations, evolution via rate equations and via equilibria, is presented, focusing on efficient solution of these matrix equations, by making best use of the sparseness of these matrices.

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.
