In this review the quenching of the weak axial-vector coupling strength, g A, is discussed in
nuclear β and double-β decays. On one hand, the nuclear-medium and nuclear many-body …

We study scenarios for chiral symmetry restoration and deconfinement at finite temperature
and/or density, based on assuming universal scaling relations fort some hadron masses. We …

A shell-model study is made of first-forbidden β decay and related processes in A= 205–212
nuclei. The interactions used are modifications of the Kuo-Herling realistic effective …

Quenching of the weak axial strength g A is discussed and relations of this quenching to the
nuclear matrix elements of double beta decays are highlighted. An analysis of Gamow-Teller …

We have investigated the 0− Y g 96 β decay to the levels of Zr 96. A detailed decay scheme
comprised of 63 γ rays and 44 energy levels has been obtained from γ singles, γ …

A shell-model study is made of first-forbidden β decay in A= 205–212 nuclei. A least-squares
fit for eighteen ΔJ= 0 and 1 decays gave a scaling factor for the rank-one contributions of …

Partial restoration in nuclear matter of the chiral symmetry of QCD is discussed together with
some of its possible signals. Estimates of corrections to the leading, linear dependence of …

It is shown that the recently reported strong enhancement of the axial-charge matrix element
in first-forbidden β decay in heavy nuclei (A= 205–212) can be simply explained in terms of …

The enhancement factor ϵmec= 1+ δmec, defined as the ratio of the axial-charge matrix
element in first-forbidden beta decay to its impulse-approximation value, is calculated in a …

The effects of the enhancement of the axial-charge matrix element γ 5 were studied in
medium heavy and heavy nuclei for first-forbidden J+↔ J− decay transitions using the …
