Remember that [G.sub.F] is the Fermi coupling constant, [C.sub.A] [equivalent] 1.26 is the axal-vector weak coupling constant of a neutron, and [N.sub.v] = 3 is the number of neutrino flavors; [p.sub.F] is the Fermi momentum of neutrons, [m.sup.*] = [p.sub.F] / [v.sup.F] is the effective neutron mass; m is bare nucleon mass, [T.sub.9] = T/([10.sup.9]K), [k.sub.B] is the Boltzmann constant, and
Lately, in order to reduce the effect of the high-momentum component of strong nuclear force on finite nuclei properties, a Fermi momentum cutoff has been imposed on both average effective interactions and density- and channel-dependent ones [76, 77].
It should be noted that k's are topped to the Fermi momentum, [K.sub.F]([rho]) = [(6[[pi].sup.2][rho]/v).sup.1/3], with v being degeneracy parameter of nucleons.

This leads to a spectrum that is continuous at the Fermi momentum, which provided the name "continuous choice" for this approach.
The Pauli operator Q([p.sub.1], [p.sub.2]) restricts the intermediate states to particle states with momenta [p.sub.1], [p.sub.2], which are above the corresponding Fermi momentum. However, the single-particle spectrum is often parameterized in the form of an effective mass
The corrections of the single-particle energies due to the [DELTA][[summation].sup.2h1p] term are larger for momenta below the Fermi momentum and tend to zero for momenta above [k.sub.F].
