Direct proton decay of 147 Tm
TL;DR: Using on-line mass separation of evaporation residues from the reaction 58Ni + 92Mo → 150Yb*, a proton line of 1055 ± 6 keV energy and 056 ± 004 s half-life was observed as discussed by the authors.

TL;DR: A neutron deficient isotope Am-235 has been produced via the reaction Pu-238(p,4n) am-235 by 35 MeV proton bombardment of Pu- 238 as discussed by the authors.

Li Zhankui,Xu Shuwei,Yu Yong,Xie Yuanxiang,Wang Chunfang,Xing Jianping,HU Qingyuan Pan Qiangyan,LI Shihong,Chen Hongyan +8 more
TL;DR: In this article, the P-delayed proton spectrum of 89 Ru populating the lowlying states in 88 Mo was obtained, and the final state proton branching ratios to the low-lying 2 + and 4 + states in 8 Mo were estimated to be 100: 6.5 MeV.

A statistical theory of nuclear neutrino capture
TL;DR: In this article, a statistical theory is proposed for the calculation of the total capture cross section of a neutrino by a nucleus and close references are made to the statistical theory of β-decay and electron capture developed by Yamada and his collaborators.

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.
