Beta-decay half-lives calculated on the gross theory
TLDR
In this paper, the gross theory was used to calculate the Beta-decay half-life of all the isotopes between the proton-drip and neutron drip lines with Z = 3 to Z = 100.About:

Nuclear Data Sheets for A = 106
D. De Frenne,A. Negret +1 more
TL;DR: In this paper, the 1994 evaluation on mass A = 106 has been revised, taking into account all data available before May 2007, and detailed experimental information is presented from the neutron rich nucleus {sup 106}Y to the neutron deficient nucleus [sup 106]Te nucleus.

Current quests in nuclear astrophysics and experimental approaches
TL;DR: In this article, a review summarizes current problems and questions in experimental nuclear astrophysics, focusing on the present need for experimental data, emphasizing novel methods and approaches, and the potential use of radioactive ion beams and their importance for characterizing explosive nucleosynthesis in X-ray bursts and supernovae.

Current status of r -process nucleosynthesis
Toshitaka Kajino,Toshitaka Kajino,Wako Aoki,A. B. Balantekin,Roland Diehl,Roland Diehl,Michael Famiano,Grant J. Mathews +7 more
TL;DR: The rapid neutron capture process ( r-process) is believed to be responsible for about half of the production of the elements heavier than iron and contributes to abundances of some lighter nuclides as well as mentioned in this paper.

Direct and beta-delayed proton decay of very neutron-deficient rare-earth isotopes produced in the reaction 58 Ni+ 92 Mo

TL;DR: Using on-line mass separation of evaporation residues from the reaction 58Ni +92Mo→150Yb*, a proton line of 1,055±6 keV energy and 0.42±0.10 s half-life was observed at mass number 147. The origin of this activity is very likely the direct proton decay of147Tm.

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.
