By assuming that the axial-vector current is partially conserved, a relationship is obtained
between the phenomenological meson-exchange operator in beta decay and the two-body …

It is pointed out that two forms of the induced pseudotensor current, equivalent on the mass
shell, lead to quite different results in nuclei for δ=(ft) β+/(ft) β-− 1 which was used by …

The hypothesis of partially conserved axial-vector current (PCAC) is applied to relate the
threshold production amplitude for the process α→ β+ π+ to the meson-exchange …

In order to derive in a convincing manner the formula of Goldberger and Treiman for the rate
of charged pion decay, we consider the possibility that the divergence of the axial vector …

An estimate is made, using no-recoil meson theory, of the π-mesonic exchange
contributions to the beta-decay of nuclei assuming that such effects only contribute to the …

The theory of the beta decay of complex nuclei, N i→ N f+ e−+ ν e, is developed on the basis
of a treatment which considers the nuclei involved (N i) as" elementary" particles and applies …

pi hole in 207Pb. Since 07Pb is a very good 4 Z-hole configuration and 206Pb a very good
closed- shell nucleus [7] *, this exper Page 1 Volume 21, number 6 PHYSICS LETTERS 1 …

1. Introduction.—We have derived a sum rule expressing the axial-vector coupling-constant
renormalization in P decay in terms of off-mass-shell pion-proton total cross sections. This …

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 …

A comparison of the ft values for the H 3 and neutron β-decays is used to estimate the
magnitude of mesonic exchange effects in the exial vector interaction. These effects are …
