Four-Nucleon Bound State Calculations with Exact Treatment of (2+2)-Subsystem Contributions

摘要

As an addendum to a previous paper (Phys. Rev. C26, 228 (1982)), we report on four-boson binding energy calculations which use separable expansions only for the (3+1)-subsystem amplitudes. In contrast to the previous procedure, the amplitudes of the (2+2)-subsystems are now incorporated exactly, according to the four-body formulation of Haberzettl and Sandhas, with the help of a convolution method. Our investigation clearly shows the feasibility of such a treatment. (ERA citation 08:042778)
