Monte Carlo approach to sequential {gamma}ray emission from fission fragments
Abstract
A Monte Carlo simulation of the fission fragment statistical decay based on a sequential neutron followed by {gamma}ray emission is proposed. The {gamma}ray energy spectrum is calculated as a function of the mass of the fission fragments and integrated over the whole mass distribution. The prompt {gamma}ray multiplicity distribution, both the average number of emitted {gamma} rays and the average {gamma}ray energy as a function of the mass of the fission fragments [respectively, N{sub {gamma}}(A) and <{epsilon}{sub {gamma}}>(A)], are also assessed. The {gamma}{gamma} correlations emitted from both light and heavy fragments are calculated as well as correlations between {gamma}ray energies. Results are reported for the neutroninduced fission of {sup 235}U (at 0.53 MeV neutron energy) and for the spontaneous fission of {sup 252}Cf.

We have implemented a Monte Carlo simulation of fission fragment statistical decay by sequential neutron emission. Within this approach, we calculate the centerofmass and laboratory prompt neutron energy spectra as a function of the mass of fission fragments and integrated over the whole mass distribution. We also assess the prompt neutron multiplicity distribution P({nu}), both the average number of emitted neutrons and the average neutron energy as a function of the mass of the fission fragments [respectively {nu}(A) and <E>(A)]. We investigate the average total energy available for prompt {gamma}ray emission as a function of the mass of the fissionmore »

Investigation of phenomenological models for the Monte Carlo simulation of the prompt fission neutron and {gamma} emission
A Monte Carlo simulation of the fission fragment deexcitation process was developed in order to analyze and predict postfissionrelated nuclear data which are of crucial importance for basic and applied nuclear physics. The basic ideas of such a simulation were already developed in the past. In the present work, a refined model is proposed in order to make a reliable description of the distributions related to fission fragments as well as to prompt neutron and {gamma} energies and multiplicities. This refined model is mainly based on a massdependent temperature ratio law used for the initial excitation energy partition of themore » 
Monte Carlo calculation of the deexcitation of fission fragments in the spontaneous fission of /sup 252/Cf
The consequences of the evaporation of prompt neutrons and ..gamma.. rays from primary fission fragments in the spontaneous fission of /sup 252/Cf have been examined by a Monte Carlo method. A semiempirical mass equation and experimental values of total kinetic energies are used to obtain the sum of excitation energies of complementary fragments. The division of this energy between complementary fragments is determined by the twospheroid model for the scission configuration. The prompt neutron multiplicity distribution gives a value of 3.68 for the average number of prompt neutrons in /sup 252/Cf (sf). Calculated values of the average number of promptmore » 
The Monte Carlo Multiply Scattered Components (MCMSC) approach for natural gammaray log interpretation
A new approach called the Monte Carlo Multiply Scattered Component (MCMSC) approach has been developed for natural gammaray logging tool interpretation. It consists of first determining individual scatter component library gammaray spectra for each of the three sources of natural gamma radiation *({sup 40}K, U, and Th) for a reference sample by Monte Carlo simulation. Then these scatter component library spectra, normalized to unit area, are used to obtain coefficients by the library leastsquares (LLS) method with the natural radioisotope library spectra for a range of sample parameters such as borehole fluid density and composition as well as formation densitymore » 
CONSTRAINTS ON THE LORENTZ INVARIANCE VIOLATION WITH GAMMARAY BURSTS VIA A MARKOV CHAIN MONTE CARLO APPROACH
In the quantum theory of gravity, for photons we expect the Lorentz Invariance Violation (LIV) and the modification of the dispersion relation between energy and momentum. The effect of the energydependent velocity due to the modified dispersion relation for photons was studied in the standard cosmological context by using a sample of gammaray bursts (GRBs). In this paper we mainly discuss the possible LIV effect of using different cosmological models for the accelerating universe. Due to the degeneracies among model parameters, the GRBs’ time delay data are combined with the cosmic microwave background data from the Planck firstyear release, themore »
