Yukawa form factor

Conventional spherical shell model calculations have been undertaken to describe 90 88zr and 90 88y in these large scale calculations valence orbitals included If5/2 2P3/2 2Pl/2 and 199/2 The d5/2 orbital was included for 98Y and for high-spin calculations in 98Zr. Restrictions were placed on orbital occupancy so that the basis set amounted to less than 2b,000 Slater determinants. Calculations were done with a local, state independent, two-body interaction with single Yukawa form factor. Predicted excitation energies and electromagnetic transition rates are compared with recent experimental results. 

Spherical shell-model calculations were undertaken of these nuclei, in order to gain information on their nuclear structure. The calculations reported here were done with a local, state independent two-body interaction with a single Yukawa form factor,... 

This is the form factor for a Yukawa shaped density distribution, namely... 

In the numerical studies a tangent SFC chain model with zero bending energy is employed (which is the closest continuum chain model used in the lattice simulations). For simplicity, the single-chain structure factor is taken to be ideal (blend composition and density independent), and temperature independent. The tail potentials are taken to be of a Yukawa form... 

This potential has the form of the charge q times a screened Coulomb potential (Yukawa potential, e "Jer ) multiplied by what we have termed an ion exclusion factor, y [43]. This suggests that ion exclusion might be incorporated into DESMO using an ansatz of the form [43]...
