چکیده
The effect of setting all T=0 two body interaction matrix elements equal to a constant (or zero) in shell model calculations (designated as < T = 0 >= 0) are investigated. Despite the apparent severity of such a procedure, one gets fairly reasonable spectra. We find that using < T = 0 >= 0 in single j shell calculations degeneracies appear e.g. the I =

Abstract In the nuclear f7/2 shell, the nucleon–nucleon interaction can be represented by the eight values E(J) = 〈(f2 7/2) J |V |(f2 7/2) 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 which we attempt to explain in this work. We also give more detai...

Talmi's method of calculating coefficients of fractional parentage to states forbidden by the Pauli principle. Abstract In a previous work we studied the effects of setting all two body T=0 matrix elements to zero in shell model calculations for 43 Ti (43 Sc) and 44 Ti. The results for 44 Ti were surprisingly good despite the severity of this approximation. We found degeneracies in this approxi...

We demonstrate that any scale-invariant mechanics of one variable exhibits not only 0+1 conformal symmetry, but also the symmetries of a full Virasoro algebra. We discuss the implications for the adS/CFT correspondence.
