Title: Degeneracies when only T=1 two-body interactions are present

Abstract

In the nuclear f{sub 7/2} shell, the nucleon-nucleon interaction can be represented by the eight values E(J)=<(f{sub 7/2}{sup 2}){sup J}|V|(f{sub 7/2}{sup 2}){sup J}>,J=0,1,...,7, where for even J the isospin is 1, and for odd J it is 0. If we set the T=0 (odd J) two-body matrix elements to zero (or to a constant), we find several degeneracies that we attempt to explain in this work. We also give more detailed expressions than previously for the energies of the states in question. New methods are used to explain degeneracies that are found in {sup 45}Ti (I=25/2{sup -} and 27/2{sup -}), {sup 46}V (I=12{sub 1}{sup +} and 13{sub 1}{sup +}, as well as I=13{sub 2}{sup +} and 15{sup +}), and {sup 47}V (I=29/2{sup -} and 31/2{sup -})

  • It is shown that the enhancement of the D/sup 0/ ..-->.. K-bar/sup 0/..pi../sup 0/ weak amplitude induced by final-state interactions is tempered by constraints of the ..delta..T=1 rule for Cabibbo-allowed nonleptonic charm decay.
  • It has previously been observed that protease inhibitors suppress radiation transformation in vitro. The present study showed that a 24 h treatment with the protease inhibitor antipain at five days post-irradiation was sufficient to significantly suppress radiation transformation. Comparable experiments performed with cycloheximide, an inhibitor of protein synthesis, showed that this metabolic inhibitor could suppress radiation transformation when present immediately following the X-ray exposure but not when present for one day at five days post-irradiation. These results suggest that antipain is suppressing an ongoing cellular process occurring in response to X-irradiation.

  • The integral equation for the four-fermion vertex function GAMMA in a many-body medium is solved in the t-channel. The usual RPA is extended by taking into account retarded and advanced effects of the particle-hole interaction. Specific attention is paid to the exchange of pp- and hh-vibrations between the ph-pair. Other types of dynamic interaction such as ph-phonons propagating in time are also discussed. The physical relevance of dynamic interactions is pointed out by comparing with other extensions of the RPA. Situations in which dynamic interactions are expected to be important are discussed.
  • Calculations of the spectra of various even-even nuclei in the fp shell ({sup 44}Ti, {sup 46}Ti, {sup 48}Ti, {sup 48}Cr, and {sup 50}Cr) are performed with two sets of two-body interaction matrix elements. The first set consists of the matrix elements of the FPD6 interaction. The second set has the same T=1 two-body matrix elements as the FPD6 interaction, but all the T=0 two-body matrix elements are set equal to zero (T0FPD6). Surprisingly, the T0FPD6 interaction gives a semireasonable spectrum when compared to FPD6 (or else this method would make no sense). A consistent feature for even-even nuclei, e.g., {supmore » 44,46,48}Ti and {sup 48,50}Cr, is that the reintroduction of T=0 matrix elements makes the spectrum look more rotational than when the T=0 matrix elements are set equal to zero. The odd-odd nucleus {sup 46}V is also discussed. In general, but not always, the inclusion of T=0 two-body matrix elements enhances the B(E2) rates.« less
