[en] The interaction cross sections of high energy nucleus-nucleus scattering have been studied with the Glauber Model and Hartree-Fock like variational calculation for the nuclear structure. It is found that the experimental interaction cross sections of the light unstable nucleus-stable nucleus scatterings measured by INS-LBL collaboration are well reproduceable. (author)

[en] The interaction mean free path of the high energy nucleus in the emulsion is studied with the Glauber Model and Hartree-Fock type variational calculation for the nuclear structure. It is found that the experimentally observed interaction mean free paths are well reproduceable. It is also found that the interaction radius of the projectile nucleus is determinable with the emulsion experiment. (author)

[en] The interaction cross sections of medium and high energy nucleus-nucleus scattering are studied with the Glauber Model and Hartree-Fock type variational calculation. The interaction cross sections so obtained nicely satisfy the additivity relationship, which in turn suggests the existence of a nuclear interaction radius in nucleus-nucleus scattering. With the calculated interaction cross sections, the nuclear interaction mean free path of high energy nucleus in emulsion is studied, and the results agree very well with experimental data. It is found that the interaction radius of the projectile nucleus can also be determined from emulsion experiment. (author)

[en] Fast neutron emission from the giant quadrupole resonance region is studied. To explain the characteristic neutron angular distribution observed by coincidence experiments, we investigated the escape process of the giant quadrupole resonance and the contribution from the direct knockout reaction.

[en] We develop a time-dependent theory of heavy-ion collisions which consistently treats the relative and the intrinsic motions by coupled equations derived from the many-body von Neumann equation. The structure of the equations determining the mean trajectory and the fluctuations of the relative motion is the same as that of the corresponding equations in the known linear response theory. The present theory differs, however, from the linear response theory, in that it presumes neither weak coupling between the relative motion and the intrinsic excitations, nor the canonical distribution function for the density operator of the intrinsic motions. We apply the theory especially to deep inelastic collisions where the relative motion couples to intrinsic excitations through a stochastic hamiltonian. Based on the stochastic assumption, we study the properties of the Green functions that take into account the higher order effects of the coupling hamiltonian. We then discuss, in particular, the effects of the Green functions on the time evolution of the intrinsic state, which is described in terms of a coarse-grained master equation, the friction tensor and fluctuation dissipation theorems.

[en] We present a microscopic analysis of the nuclear spin response to proton excitation by examining the specific case of the ⁴⁰Ca (p-rvec, p-rvec ') reaction. Recent results indicate that the spin-flip probability decreases with an increase in the incident proton energy from E/sub p/=319 to 800 MeV but otherwise maintains the essential features of an enhancement at high excitation and a quenching at low excitation. We show that this feature is consistent with nuclear structure effects and is not likely to depend on the particular choice of proton beam energy. We also suggest that the decrease in spin-flip cross section with increasing E/sub p/ is directly linked to the energy dependence of the t-matrix coefficients and conclude by presenting predictions for cross sections at lower incident proton energy

[en] The equations of motion for a massive spin-3/2 Rarita-Schwinger field in a finite-range, central, Lorentz scalar potential are developed. It is shown that the resulting density may not be everywhere positive definite. (author)

[en] The response of the nuclear many body system to a spin-isospin dependent probe is investigated in the random phase approximation with the objective of studying the mechanism for the near equality of the transverse and longitudinal components of the spin response function observed in recent proton scattering experiments. We examine in particular the angular momentum dependence of R/sub L//R/sub T/ as a means to investigate the spatial origin of the various contributions to this ratio. The physical picture which emerges from our work suggests that two effects conjure themselves in producing R/sub L/--R/sub T/. At the nuclear surface probed by the proton beam, the smaller nuclear density reduces the effect of the difference between the longitudinal and transverse components of the particle-hole interaction. More importantly however, transverse-longitudinal mixing is also predominant at the nuclear surface producing altogether calculated values for R/sub L//sub X/R/sub T/ within the error bars of the experimental data
