The yields and velocity distributions of heavy residues and fission fragments from the reaction of 20 MeV/nucleon 197 Au + 90 Zr have been measured using the MSU A1200 fragment separator. A bimodal distribution of residues is observed, with one group, resulting from peripheral collisions, having fragment mass numbers A=160– 200 while the other group, resulting from " hard " collisions, has A=12...

We found ENDF/B-VIII.0 caused the following problems through our analyses of iron insitu experiment at JAEA/FNS; 1) neutron flux 1 - 10 keV is overestimated more in shallower region assembly, 2) reaction rate 115In (n,n’)115mIn underestimated deeper region, 3) above MeV region. The reasons for these were investigated detail and it was specified that inelastic scattering data 56Fe ENDF/BVIII. 0 ...
Following the idea that the electromagnetic and nuclear distributions behave similarly for large momentum transfers (as introduced by Wu and Yang and further developed by A.barbanel, Drell and Gilman) we examine the possibility of relating the deep inelastic electron scattering to large momentum transfer and high energy inelastic protonproton reactions.

In this paper, we review the roles of collective modes in nuclear reactions. We emphaize the strong couplings of various collective states with the monopole and quadrupole motions. In inelastic excitation, these couplings can be seen as an important source of anharmonicity in the multiphonon spectrum. In fusion reaction, the breathing and quadrupole motions strongly affects the oscillation of p...
We discuss how the excitation of high-frequency modes in adsorbed molecules may result in motion (e.g., rotation, translation, or dissociation) of the molecules. Our study is based on rate equations and considers one- and two-vibrational excitation processes, corresponding to linear and quadratic dependences of the reaction rate on the tunneling current in the case the scanning tunneling micros...
Inclusive electron scattering from nuclei at large x and Q2 is the result of a reaction mechanism that includes both quasi–elastic scattering from nucleons and deep inelastic scattering from the quark consitituents of the nucleons. Data in this regime can be used to study a wide variety of topics, including the extraction of nuclear momentum distributions, the influence of final state interacti...
