A quantitative understanding of the weak nuclear response is a prerequisite for the computer simulations of astrophysical phenomena like supernovæ explosions and neutron star cooling. In order to reduce the systematic uncertainties associated with the simulations, a consistent framework, able to take into account dynamical correlation effects, is needed to compute neutrino-nucleon and neutrino-...

Abstract. We present a novel approach for the treatment of realistic nucleonnucleon interactions in nuclear many-body systems. A unitary correlation operator is used to explicitly introduce short-range central and tensor correlations in many-body states. The resulting correlated interaction serves as an effective interaction in nuclear structure calculations. Results for Lithium isotopes includ...

The recent experimental observations of triple tracks in solid-state nuclear track detectors, CR-39, during Pd/D co-deposition experiments indicate that the triple tracks are due to∼14 MeV neutrons, which appear to originate from “hot” fusion reaction D(t,n)He. Nuclear theory interpretation of the origin of ∼14 MeV neutrons is presented in terms of a sub-threshold resonance reaction involving (...

Coulomb dissociation is an especially simple and important reaction mechanism. Since the perturbation due to the electric field of the nucleus is exactly known, firm conclusions can be drawn from such measurements. Electromagnetic matrix elements and astrophysical S-factors for radiative capture processes can be extracted from experiments. We describe the basic theory, new results concerning hi...
