We investigate the binding energy per nucleon and hadron properties in infinite and homogeneous nuclear matter within the framework of the in-medium modified Skyrme model. We first consider the medium modifications of the single hadron properties by introducing the optical potential for pion...
In a study motivated by a recent experiment, the distribution of electric dipole strength in the neutron-rich Ni 68 isotope was computed using a relativistic random-phase approximation with a set of effective interactions that—although well calibrated—predict significantly different values...
Gamma-ray telescopes in orbit around the earth are searching for evidence of the elusive radionuclide Na 22 produced in novae. Previously published uncertainties in the dominant destructive reaction, Na 22 ( p , γ ) Mg 23 , indicated new measurements in the proton energy range of 150 to 300 keV...
All possible ternary fragmentations in fission of Cf 252 are studied in collinear configuration within a spherical approximation using the recently proposed “three cluster model.” The potential energy surface of collinear configuration exhibits a strong valley around Ca 48 and its neighboring...
The fission fragment mass angle correlations and mass ratio distributions have been investigated for the two systems O 16 + Au 197 and Al 27 + W 186 , leading to the same compound nucleus Fr 213 around the Coulomb barrier energies. Systematic analysis of the variance of the mass distributions as...
Prompt fission neutron spectra from U 235 and Pu 239 were measured for incident neutron energies from 1 to 200 MeV at the Weapons Neutron Research facility (WNR) of the Los Alamos Neutron Science Center, and the experimental data were analyzed with the Los Alamos model for the incident neutron...
The cross section for radiative thermal neutron capture on 3 He ( 3 He + n → 4 He + γ ; known as the hen reaction) is calculated based on heavy-baryon chiral perturbation theory. The relevant M1 operators are derived up to next-to-next-to-next-to-leading order (N L 3 O). The initial and final...
Shear η and bulk ζ viscosities are calculated in a quasiparticle model within a relaxation-time approximation for pure gluon matter. Below T c , the confined sector is described within a quasiparticle glueball model. The constructed equation of state reproduces the first-order phase transition...
