The Detection Statistics of Neutrons and Photons Emitted from a Fissile Sample

The purpose of this paper is to present new analytical derivations to describe the emission and detection statistics of neutrons and photons generated in and emitted from fissile samples, with absorption included. The results of the analytical approach are compared with and validated by corresponding Monte Carlo simulations. The joint statistics of the generated and detected neutrons and photon...

Medusae Fossae-elysium Region, Mars: Depression in the Hend/odyssey Map of Mars Epithermal Neutrons

Introduction. The first data from the Gamma Ray Spectrometer (GRS) onboard Mars Odyssey spacecraft showed that the low neutron fluxes characterize both subpolar regions of Mars [1-3]. The low neutron fluxes mean the presence of hydrogen-rich soils and have been i nterpreted as an indication on abundant water ice in these areas. The equatorial region of Mars (equatorward of ~50 o) is characteriz...

Direct radiative capture of p-wave neutrons.

The neutron direct radiative capture (DRC) process is investigated, highlighting the role of incident p-wave neutrons. A set of calculations is shown for the C(n; ) process at incoming neutron energies up to 500 keV, a crucial region for astrophysics. The cross section for neutron capture leading to loosely bound s, p and d orbits of C is well reproduced by the DRC model demonstrating the feasi...

Dynamic ultraslow optical-matter wave analog of an event horizon.

We investigate theoretically the effects of a dynamically increasing medium index on optical-wave propagation in a rubidium condensate. A long pulsed pump laser coupling a D2 line transition produces a rapidly growing internally generated field. This results in a significant optical self-focusing effect and creates a dynamically growing medium index anomaly that propagates ultraslowly with the ...

Wave Propagation in Micropolar Thermoelastic Diffusion Medium

The present investigation is concerned with the reflection of plane waves from a free surface of a micropolar thermoelastic diffusion half space in the context of coupled theory of thermoelastic diffusion. The amplitude ratios of various reflected waves are obtained in a closed form. The dependence of these amplitude ratios with an angle of propagation as well as other material parameter are sh...
