A Monte Carlo study was carried out to determine the influence of the effective scattering mass ( M e ) of the atoms on the neutron density profile inside and outside the sample illuminated by a thermal neutron beam as in large-sample prompt-gamma neutron activation analysis (LS-PGNAA). ...

The higher the mass of the particle, the narrower the dose-weighted lineal energy spectra and the larger the shift to high lineal energy values. A shift of the spectra in high y values would represent an increase in the aggressiveness of the event, i.e. inducing more frequently lethal ...

After 6 months of operations, totaling 58.6 live days and 5.4 kg of fiducial mass, XENON10 set the best upper limits at the time. Finding a spin-independent WIMP-nucleon cross-section sigmachi = 8.8 x 10 -44 cm2 and a spin-dependent WIMP-neutron cross-section sigma chi = 1.0 x 10-...
