Continuum-state and bound-state β - -decay rates of the neutron

Continuum-state and bound-state β - -decay rates of the neutron For the β - -decay of the neutron we analyze the continuum-state and bound-state decay modes. We calculate the decay rates, the electron energy spectrum for the continuum-state decay mode, and angular distributions of the decay probabilities for the continuum-state and bound-state decay modes. The theoretical results are obtained for the new value for the axial coupling constant g A = 1 . 2750 ( 9 ) , obtained recently by H. Abele Prog. Part. Nucl. Phys. 60 , 1 (2008) from the fit of the experimental data on the coefficient of the correlation of the neutron spin and the electron momentum of the electron energy spectrum of the continuum-state decay mode. We take into account the contribution of radiative corrections and the scalar and tensor weak couplings. The calculated angular distributions of the probabilities of the bound-state decay modes of the polarized neutron can be used for the experimental measurements of the bound-state β - -decays into the hyperfine states with total angular momentum F = 1 and scalar and tensor weak coupling constants. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Review C American Physical Society (APS)

Abstract

For the β - -decay of the neutron we analyze the continuum-state and bound-state decay modes. We calculate the decay rates, the electron energy spectrum for the continuum-state decay mode, and angular distributions of the decay probabilities for the continuum-state and bound-state decay modes. The theoretical results are obtained for the new value for the axial coupling constant g A = 1 . 2750 ( 9 ) , obtained recently by H. Abele Prog. Part. Nucl. Phys. 60 , 1 (2008) from the fit of the experimental data on the coefficient of the correlation of the neutron spin and the electron momentum of the electron energy spectrum of the continuum-state decay mode. We take into account the contribution of radiative corrections and the scalar and tensor weak couplings. The calculated angular distributions of the probabilities of the bound-state decay modes of the polarized neutron can be used for the experimental measurements of the bound-state β - -decays into the hyperfine states with total angular momentum F = 1 and scalar and tensor weak coupling constants.
