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 neutron-induced fission of {sup 235}U (at 0.53 MeV neutron energy) and for the spontaneous fission of {sup 252}Cf.

Monte Carlo approach to sequential neutron emission from fission fragments

Journal Article Lemaire, S. ; Talou, P. ; Kawano, T. ; ... - Physical Review. C, Nuclear Physics

We have implemented a Monte Carlo simulation of fission fragment statistical decay by sequential neutron emission. Within this approach, we calculate the center-of-mass 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 »« less

Investigation of phenomenological models for the Monte Carlo simulation of the prompt fission neutron and {gamma} emission

Journal Article Litaize, O. ; Serot, O. - Physical Review. C, Nuclear Physics

A Monte Carlo simulation of the fission fragment deexcitation process was developed in order to analyze and predict postfission-related 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 mass-dependent temperature ratio law used for the initial excitation energy partition of themore »« less

CONSTRAINTS ON THE LORENTZ INVARIANCE VIOLATION WITH GAMMA-RAY BURSTS VIA A MARKOV CHAIN MONTE CARLO APPROACH

Journal Article Pan, Yu ; Gong, Yungui ; Cao, Shuo ; ... - Astrophysical Journal

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 energy-dependent velocity due to the modified dispersion relation for photons was studied in the standard cosmological context by using a sample of gamma-ray 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 first-year release, themore »« less

MONTE CARLO SIMULATIONS OF THE PHOTOSPHERIC EMISSION IN GAMMA-RAY BURSTS

Journal Article Begue, D. ; Siutsou, I. A. ; Vereshchagin, G. V. - Astrophysical Journal

We studied the decoupling of photons from ultra-relativistic spherically symmetric outflows expanding with constant velocity by means of Monte Carlo simulations. For outflows with finite widths we confirm the existence of two regimes: photon-thick and photon-thin, introduced recently by Ruffini et al. (RSV). The probability density function of the last scattering of photons is shown to be very different in these two cases. We also obtained spectra as well as light curves. In the photon-thick case, the time-integrated spectrum is much broader than the Planck function and its shape is well described by the fuzzy photosphere approximation introduced by RSV.more »« less

MONTE CARLO RADIATION TRANSFER SIMULATIONS OF PHOTOSPHERIC EMISSION IN LONG-DURATION GAMMA-RAY BURSTS

Journal Article Lazzati, Davide - Astrophysical Journal

We present MCRaT, a Monte Carlo Radiation Transfer code for self-consistently computing the light curves and spectra of the photospheric emission from relativistic, unmagnetized jets. We apply MCRaT to a relativistic hydrodynamic simulation of a long-duration gamma-ray burst jet, and present the resulting light curves and time-dependent spectra for observers at various angles from the jet axis. We compare our results to observational results and find that photospheric emission is a viable model to explain the prompt phase of long-duration gamma-ray bursts at the peak frequency and above, but faces challenges when reproducing the flat spectrum below the peak frequency.more »« less
