Angular Correlation of the Continuous Radiation Accompanying Beta-Decay

Abstract

LETTERS TO THE EDITORQ-value of -(1.006:4=0.010) Mev has been given 3 corresponding to a mass difference of (0.22±0.01) Mev.The new method of determining the energy-release in electron capture processes may be applied even in some cases where the disintegration goes over an excited level of the daughter nucleus with the emission of a nuclear 7-ray. A more detailed account will be published in Helvetica Physica Ada. We thank Professor P. Scherrer for his interest in this work.

Studies on inner bremsstrahlung from a few beta-emitting isotopes

“…The theory for IB emission from allowed β transitions was deduced by Knipp and Uhlenbeck (1936) and independently by Bloch (1936), and is popularly known as the KUB theory. Chang and Falkoff (1949) (CF), Madansky et al (1951), Lewis and Ford (1957) (LF) and Gebhardt (1968) extended the KUB theory to include the forbidden character of β decay. LF incorporated a first-order approximation of the Fermi function.…”

Study of the continuous internal bremsstrahlung spectrum from 204Tl by using singular value decomposition

“…Later, this theory was modified by Nilsson (1956), Lewis and Ford (1957). Chang and Falkoff (1949), Madansky. et al, (1951), and later Ford and Martin (1969) have studied the effect on the spectra of the nature of β − interaction as well as the degree of being forbidden on the IB spectra.…”

Deconvolution of continuous internal bremsstrahlung spectra of 32P, 85Kr and 143Pr

“…Later, this theory was elaborated, taking into account the Coulomb effects, by Nilsson, 3 Lewis and Ford 4 and others. Chang and Falkoff, 5 Madansky et al, 6 and later Ford and Martin 7 have studied the effect on the spectra of the nature ofˇ-interaction as well as the degree of forbiddenness on the IB spectra. Ford and Martin included the so-called detour transitions in the IB process for for-biddenˇ-decays.…”
