An exact fermion model with monopole and quadrupole pairing

A hamiltonian for valence nucleons is shown to give exact eigenstates that consist of monopole and quarupole pair creation operators acting on u unpaired nucleons. he quantum numbers and eigenenergies for u = 0 are shown to be the same as those given by the interacting boson approximation in the vibrational limit.     

Test of nuclear wave functions for pseudospin symmetry

Using the fact that pseudospin is an approximate symmetry of the Dirac Hamiltonian with realistic scalar and vector mean fields, we derive the wave functions of the pseudospin partners of eigenstates of a realistic Dirac Hamiltonian and compare these wave functions with the wave functions of the Dirac eigenstates.     

Influence of nucleon mean-free paths on intranuclear cascade results

Results of the intranuclear cascade calculation are compared for 62 MeV protons on ⁸⁹Y and ⁵⁴Fe targets. Standard calculations and results with mean free paths increased fourfold are compared. The latter set gives poorer results versus experimental data due to an overestimate of nuclear transparency.
