Lowmomentum nucleonnucleon interactions and shellmodel calculations
Abstract
In the last few years, the lowmomentum nucleonnucleon (NN) interaction V{sub lowk} derived from freespace NN potentials has been successfully used in shellmodel calculations. V{sub lowk} is a smooth potential which preserves the deuteron binding energy as well as the halfonshell T matrix of the original NN potential up to a momentum cutoff {lambda}. In this paper, we test a new lowmomentum NN potential derived from chiral perturbation theory at nexttonexttonexttoleading order with a sharp lowmomentum cutoff at 2.1 fm{sup 1}. Shellmodel calculations for the oxygen isotopes using effective Hamiltonians derived from both types of lowmomentum potential are performed. We find that the two potentials show the same perturbative behavior and yield very similar results.

Hyperonnucleons interactions constructed by two frameworks, the KyotoNiigata SU{sub 6} quark model and the chiral effective field theory, are compared by investigating equivalent interactions in a lowmomentum space and, in addition, by calculating hyperon singleparticle potentials in the lowestorder Brueckner theory in symmetric nuclear matter. Two descriptions are shown to give similar matrix elements in most channels after renormalizing high momentum components. Although the range of the {Lambda}N interaction is different in two potentials, the {Lambda} singleparticle potential in nuclear matter is very similar. The {Sigma}nucleus and XInucleus potentials are also found to be similar. These predictions are to bemore »

Low momentum shell model effective interactions with allorder core polarizations
An allorder summation of corepolarization diagrams using the lowmomentum nucleonnucleon interaction V{sub lowk} is presented. The summation is based on the KirsonBabuBrown (KBB) induced interaction approach in which the vertex functions are obtained selfconsistently by solving a set of nonlinear coupled equations. It is found that the solution of these equations is simplified using V{sub lowk}, which is energy independent, and using the Green's functions in the particleparticle and particlehole channels. We have applied this approach to the sdshell effective interactions and find that the results we calculated to all orders by using the KBB summation technique are remarkably similarmore » 
Shellmodel phenomenology of lowmomentum interactions
The first detailed comparison of the lowmomentum interaction V{sub lowk} with G matrices is presented. We use overlaps to measure quantitatively the similarity of shellmodel matrix elements for different cutoffs and oscillator frequencies. Over a wide range, all sets of V{sub lowk} matrix elements can be approximately obtained from a universal set by a simple scaling. In an oscillator meanfield approach, V{sub lowk} reproduces satisfactorily many features of the singleparticle and singlehole spectra on closedshell nuclei, in particular through remarkably good splittings between spinorbit partners on top of harmonic oscillator closures. The main deficiencies of pure twonucleon interactions are associatedmore » 
NUCLEONNUCLEON POTENTIAL FROM SHELL MODEL CALCULATIONS FOR DOUBLET SPLITTINGS
The residual interaction responsible for the occurrence of certain closely spaced doublets in nuclei with a p/sub 1/2/, nucleon coupled to a core of spin j is sought to be represented by an effective nucleonnucleon potential. After justifying the dropping of the hard core and the noncentral terms, the two body potential is chosen to be static, nonsingular and central in character. The radial dependence is chosen to be of the Gaussian form. The relation between the parameters of an explicitly spindependent potential and those of the general exchange mixture is pointed out. The potential parameters are fixed by comparisonmore »
