The scintillators capable of neutron detection are being the research hotspot recently. In this manuscript, we investigated possibility cerium-doped gadolinium aluminium gallium garnet (GAGG: Ce) crystal to achieve gamma discrimination through pulse shape (PSD) method. PSD is a method based on principle that waveforms scintillation light differ for different particles. experiments show it’s har...

background: in neutron interaction with matter and reduction of neutron energy due to multiple scatterings to the thermal energy range, increasing the probability of thermal neutron capture by neutron captures makes dose enhancement in the tumors loaded with these materials.   objective: the purpose of this study is to evaluate dose distribution in the presence of  10 b ,  157 gd  and  33 s  ne...

The wave function of a spheroidal harmonic oscillator without spin-orbit interaction is expressed in terms of associated Laguerre and Hermite polynomials. The pairing gap and Fermi energy are found by solving the BCS system of two equations. Analytical relationships for the matrix elements of inertia are obtained function of the main quantum numbers and potential derivative. They may be used to...

There is a growing interest in the use of neutrons for national security. The majority of work on security focuses on the use of either sealed tube DT fusors or fission sources, e.g. Cf-252. Fusion reactions enable the energy of the neutron beam to be chosen to suit the application, rather than the application being chosen based on the available neutron beam energy. In this paper we discuss sim...

Though critics of traditional epistemology agree that we need to account for the role that social factors play in inquiry, developing a viable social epistemology has proved to be difficult. According to Helen Longino, it is the processes that make inquiry possible that are social, for they require a number of people to sustain them. These processes facilitate inquiry, and ensure that the resul...

We compute the final kinetic energies of the fragments emitted in the light charged particle accompanied cold fission of 252 Cf taking into account the deformation and the finite-size effects of the fragments and integrating the equations of motion for a three-body system subjected only to Coulomb forces. The initial conditions for the trajectory calculations were derived in the frame of a defo...
