The structure of the Gamow-Teller giant resonance and consequences for beta-delayed neutron spectra and element synthesis
TL;DR: In this paper, the Gamow-Teller giant resonance structure of the β-strength function is used for calculations of β-decay half lives and production rates for heavy nuclides by astrophysical processes.

Nuclear data sheets for (even-A) A = 246 through A = 262
TL;DR: Experimental data pertaining to the nuclear structure of nuclei with even mass numbers A = 246 through A = 262 have been compiled and evaluated (the odd-A mass chains, A = 245 and A = 263, are currently being revised for publication as discussed by the authors ).

Half-lives of rp-process waiting point nuclei
TL;DR: In this article, the half-lives of various proton-rich nuclei in the mass region A = 60-90, which are involved in the astrophysical rp-process, are used as input parameters of numerical simulations in Nuclear Astrophysics.

Song-Song Xu,Z. K. Li,Y. X. Xie,Q.-Y. Pan,Weiling Huang,Xingce Wang,Yongji Yu,Yuan-Ming Xing,N.-C. Shu,Y.-S. Chen,Furong Xu,Kun Wang +11 more
TL;DR: In this paper, the experimental results were compared to the theoretical predictions of some nuclear models, resulting in the following conclusions: (1) the experimental half-lives for the predicted nuclear potential-energy surfaces calculated by means of a Woods-Saxon-Strutinsky method could reproduce the assignments, and (2) the ALICE code overestimated the production-reaction cross sections of the nine studied rare-earth nuclei.

Nuclear Data Sheets for A = 248☆
TL;DR: In this paper, detailed level schemes, decay schemes, and experimental data on which they are based are presented for all nuclei with mass number A=248, and the experimental reaction and decay data are evaluated; inconsistencies and discrepancies are noted; and adopted values are given for various level properties (including spin and parity, halflife, and configuration).

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.
