Prompt muon-induced fission: a sensitive probe for nuclear energy dissipation and fission dynamics
Volker E. Oberacker, A. Sait Umar, Feodor F. Karpeshin
Following the formation of an excited muonic atom, inner shell transitions may proceed without photon emission by inverse internal conversion, i.e. the muonic excitation energy is…
Nuclear structure near the neutron dripline: lattice HFB calculations with high-energy continuum coupling
V. E. Oberacker, A. S. Umar, E. Teran
We have developed a new Hartree-Fock-Bogoliubov (HFB) code which has been specifically designed to study ground state properties of nuclei near the neutron and proton drip lines. T…
HFB Calculations Near the Drip Lines
E. Teran, V. E. Oberacker, A. S. Umar
We present the first set of results of solving the Hartree-Fock-Bogoliubov equations, which describe the self-consistent mean field theory with pairing interaction. Calculations fo…
HFB theory for nuclei near the drip-lines: continuum coupling
V. E. Oberacker, A. S. Umar, J. Chen +1
We have developed a new HFB code that specifically addresses nuclear structure physics near the driplines. The HFB equations are solved on a two-dimensional lattice for axially sym…
Mean-field nuclear structure calculations on a Basis-Spline Galerkin lattice
Volker E. Oberacker, A. Sait Umar
Our goal is to carry out high-precision nuclear structure calculations in connection with Radioactive Ion Beam Facilities. The main challenge for the theory of drip line nuclei is…
An Investigation of Neutrino-Driven Convection and the Core Collapse Supernova Mechanism Using Multigroup Neutrino Transport
A. Mezzacappa, A. C. Calder, S. W. Bruenn +4
We investigate neutrino-driven convection in core collapse supernovae and its ramifications for the explosion mechanism. We begin with an ``optimistic'' 15 solar mass precollapse m…
