Shell Model Monte Carlo studies of neutron-rich nuclei in the 1s-0d-1p-0f shells
D. J. Dean, M. T. Ressell, M. Hjorth-Jensen +3
We demonstrate the feasibility of realistic Shell-Model Monte Carlo (SMMC) calculations spanning multiple major shells, using a realistic interaction whose bad saturation and shell…
Spin-Dependent Neutralino-Nucleus Scattering for Nuclei
M. T. Ressell, D. J. Dean
We perform nuclear shell model calculations of the neutralino-nucleus cross section for several nuclei in the A = 127 region. Each of the four nuclei considered is a primary target…
Strange Neutral Currents in Nuclei
M. T. Ressell, G. J. Mathews, M. B. Aufderheide. S. D. Bloom +1
We examine the effects on the nuclear neutral current Gamow-Teller (GT) strength of a finite contribution from a polarized strange quark sea. We perform nuclear shell model calcula…
Limit on T-Violating P-Conserving Interaction from the Decay of Fe
M. T. Ressell, J. Engel, P. Vogel
We use the experimental limit on the interference of M1 and E2 multipoles in the -decay of Fe to bound the time-reversal-violating parity-conserving vertex. Our ap…
Response of Mica to Weakly Interacting Massive Particles
J. Engel, M. T. Ressell, I. S. Towner +1
We calculate spin-dependent cross sections for the scattering from mica of hypothetical weakly interacting dark-matter particles such as neutralinos. The most abundant odd-A isotop…
Implications of Recent Nucleon Spin Structure Measurements for Neutralino Dark Matter Detection
Marc Kamionkowski, Lawrence M. Krauss, M. Ted Ressell
Predicted rates for direct and indirect detection of dark-matter neutralinos depend in general on the spin content of the nucleon. Neutralinos that are predominantly -ino are th…
