Measurements of the neutron background in a potential underground site for the Supernova Neutrino Burst Observatory (SNBO) have been made. The SNBO will ultimately be capable of detecting μ and τ neutrinos from a supernova. Furthermore, masses of t

We have measured angular distributions of the 2 H( 8 Li, 7 Li) 3 H and 2 H( 8 Li, 9 Be)n reactions at E c.m. = 1.5 to 2.8 MeV using an 8 Li- radioactive-beam technique. Astrophysical S -factors and reaction rates were calculated form the measured cro

Cross sections for the $^{8}\mathrm{Li}$(d,n${)}^{9}$Be (ground state) and $^{8}\mathrm{Li}$(d,t${)}^{7}$Li reactions, both important to primordial nucleosynthesis in the inhomogeneous models, have been measured using a radioactive beam technique. Th

A neutron-\ensuremath{\alpha}-particle coincidence experiment was performed to study breakup of $^{6}\mathrm{He}$ on a $^{209}\mathrm{Bi}$ target at an incident energy of 22.5 MeV. Direct breakup, as well as breakup through the ${2}^{+}$ excited stat

Detailed information on the decay modes of very proton-rich heavy nuclei is a prerequisite for p-process nucleosynthesis models. We have therefore measured β-delayed protons and γ-rays from mass-separated sources of 96Ag, 98Ag and 98Cd, and obtaine

The 7Be(p,γ)8B reaction plays a very important role in nuclear astrophysics, since it is the source of the high-energy solar neutrinos. However, it is not possible to measure the cross section of this reaction at solar energies (20 keV) directly so

The elastic scattering of protons on ${}^{7}\mathrm{Be}$ has been measured in the energy region from 1--3.3 MeV via the thick-target technique. The data conclusively demonstrate the existence of a ${2}^{\ensuremath{-}}$ state at an excitation energy

Recent network calculations suggest that a high temperature rp-process could explain the abundances of light Mo and Ru isotopes, which have long challenged models of p-process nuclide production. Important ingredients to network calculations involvin
