For the sake of comparison, the same calculations are performed using the Brueckner-Hartree-Fock approximation. Results of the binding energy per nucleon as a function of the density and asymmetry parameter are presented for the self-consistent Green function approach using the CD-Bonn potential. The one-body potentials for protons and neutrons are obtained from the self-consistent Green-function calculations of asymmetric nuclear matter, in particular their dependence on the degree of proton/neutron asymmetry. Mansour, Hesham Gad, Khalaf Hassaneen, Khaled S.A. Self-consistent green function calculations for isospin asymmetric nuclear matter Both the present Green's function calculation and the earlier wave function calculation give electromagnetic contributions in first-forbidden nuclear beta decay matrix elements which are of order (R 0 /lambda-dash-bar/sub C/) 2 with respect to allowed decays, where R 0 is the nuclear radius and lambda-dash-bar/sub C/ is the electron Compton wavelength In order-of-magnitude terms, the results are completely consistent with an earlier, much more complete wave- function calculation which includes spin and relativistic effects. The stationary phase points in the presence of an intense field are located in very different positions than they are in the field-free case. The calculation involves a stationary-phase approximation. The transition probability for enhancement of forbidden nuclear beta decay by an applied plane-wave electromagnetic field is calculated in a nonrelativistic spinless approximation by a Green's function method.
