The microscopic, momentum space, optical potential description of spin 1/2 x 1/2 scattering is extended to include the coupling of the singlet-triplet spin channels and
the exact handling of the Coulomb force. Computing performance in constructing
the optical potential and in solving the coupled-channels Lippmann-Schwinger equations
is enhanced by parallelization...
Much work is presently being done concerning small scale heterogeneities in the
earth's crust. These heterogeneities range from pores in sedimentary rocks up to
fluctuations in the density and seismic constants of the earth's crust with scale lengths
of kilometers. The ability to study and quantify these heterogeneities using seismic...
We exhibit long-lived resonances in scattering from two-dimensional soft cage potentials comprised of three and four Gaussian peaks. Specific low-energy resonances with very narrow width are shown to correspond to classical multiple-reflection events. These states have much larger probability densities inside the cage than outside and mimic bound states in...
Detection of reactor antineutrinos for non-proliferation applications has been researched extensively across the globe and is considered as a potential technology to remotely monitor reactor operations without any intrusions to reactor components. Reactor antineutrino detection experiments have been conducted in the past and have proven successful in detecting the changes...
Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...
Optical potential for antikaon-nucleus strong interactions are constructed using
elementary antikaon-nucleus potentials determined previously. The optical potentials
are used to determine the existence of a kaon hypernucleus. Modern three
dimensional visualization techniques are used to study model dependences, new
methods for speeding the calculation of the optical potential are developed,...
