Nuclear data sheets update for A = 210*
TL;DR: In this article, the authors evaluated spectroscopic data for all nuclei with mass number A = 210 and corresponding level schemes from radioactive decay and reaction studies, and the evaluation supersedes the earlier one by B. Harmatz (81Ha54), published in Nuclear Data Sheets 34, 735 (1981).

New neutron-rich isotope: /sup 196/Os
TL;DR: In this article, a new neutron-rich isotope, /sup 196/Os, was identified as the product of the /sup 198/Pt(n,2pn) reaction.

TL;DR: In this article, the γ-rays following β−-decay of243Np and244Np were observed following chemical isolation of neptunium isotopes from the products of the reaction of 835 MeV136Xe with244Pu.

The structure of the beta strength function in heavy nuclei and its influence on β-delayed fission
TL;DR: In this paper, the shape of the beta strength function Sβ in neutron-rich nuclei is discussed and the structure of Sβ is calculated microscopically for the Gamow-Teller βdecay of 236,238Pa and is shown to be decisive for the β-delayed fission probability PβDF.

Nuclear Data Sheets for A = 195
TL;DR: The 1978 Nuclear Data Sheets for A=195 (78HaO3) have been revised on the basis of the experimental results from the various reaction and decay studies leading to nuclides in the A =195 mass chain by the cutoff date noted below as discussed by the authors.

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.
