Deconstructing the Subprime Debacle Using New Indices of Underwriting Quality and Economic Conditions: A First Look
Momentum Distribution in Nuclear matter within a Perturbation Approximation
It is shown that the norm corrections, introduced to avoid the violation of
the constraints on the depletion of the hole states in the standard
perturbative 2p2h approach, leads in nuclear matter to a dependence of the
momentum distribution with the total nucleon number. This unphysical behavior,
which in turn makes the depletion to be non-extensive, arises from
contributions of disconnected diagrams contained in the norm. It is found that
the extensivity is again recovered when the 4p4h excitations in the ground
state are included, and a reasonable value for the total number of nucleons
promoted above the Fermi level is obtained.Comment: 11 pages, LaTeX, 5 figures, figures 1 to 3 included in the latex
