The same 6j symbols that explains the absence of a certain atomic state in LS coupling also explain the absence of certain states for a system of bosons and also for certain nuclear states in jj coupling.

We continue here to study simple matrix models of quantum mechanical Hamiltonians. The eigenvalues and eigenfunctions were associated energy levels and wave functions. Whereas previously we considered the weak coupling limits of our models, we here a

A survey of even–even nuclei in the nuclear chart showed regularities in the values of the ratio Q ( 2 1 + ) / ( B ( E 2 ) for each nucleus for which independent measurements of both the electric quadrupole moment of the 2 1 + state, Q ( 2 1 + ) ,

We perform shell model calculations using a quadrupole-quadrupole interaction (Q.Q) in a single j shell space. We show that this one-parameter interaction is a good predictor of where nuclear isomerism occurs and where it does not occur. The limitati

We consider a pentadiagonal matrix which will be described in this paper. We demonstrate practical methods for obtaining weak coupling expressions for the lowest eigenvector in terms of the parameters in the matrix, v and w. It is found that the expr

It was found experimentally that the yrast [Formula: see text] 2+, 4+ and 6+ states of 92Pd are almost equally spaced suggesting a vibrational band. We consider to what extent this should be considered as an evidence of maximum J-pairing for this nuc

We show some interesting properties of tridiagonal and pentadiagonal matrices in the weak coupling limits. In the former case of this limit the ground state wave function amplitudes are identical to the Taylor expansion coefficients of the exponentia

We discuss L=0 vs L=2 couplings, symmetries of the pairing interaction for neutrons and protons, and the Jmax interaction. We show that certain schematic interactions yield exponentially decreasing transition strengths.It is a pleasure to be able to

Whereas previous works for B(E2)'s in the even-even Ti isotopes focused on yrast transitions we here also consider inter-band transitions to a second group i.e. states like 1_{1} , 2_{2}, 3_{1} , 4_{2} , 5_{1}e.t.c.. We focus on variations from one e

Using an attractive surface delta interaction we obtain wave functions for 2 neutrons (or neutron holes) in the g 7 / 2 − d 5 / 2 model space. If we take the single particle energies to be degenerate we find that the g factors for I = 2 , 4 and 6 a
