Articles in Press, Accepted Manuscript, Available Online from 20 August 2023

  Nuclear-pumped lasers (NPL) are lasers that excite the active laser environment caused by nuclear reaction. Such lasers need ionizing radiation shielding for mixed neutron and gamma fields. In this work, a shielding system for NPL was designed which using 10B(n,α)7Li. In this simulation, we have ...  Read More

Relativistic Scattering Amplitude in the Pöschl-Teller Double Ring-Shaped Coulomb Potential

Mahdi Eshghi; Sasan Soudi; Sameer M. Khadir

Volume 2, Issue 4 , December 2021, , Pages 11-18

  The scattering problems, in the presence of an external potential field, have become highly interesting topics in relativistic and non-relativistic quantum mechanics. It is well known that the scattering of a relativistic particle in the field of a potential can be treated exactly by finding the continuum ...  Read More

Studies on Photon Buildup of the Dysprosium Doped Lithium Magnesium Borate Glasses System

Volume 2, Issue 1 , January 2021, , Pages 19-25

  The buildup factor is becoming a required parameter for exposure and energy absorption in the area of radiation physics for shielding, dosimetry, health physics and medical physics. In this research, photon buildup for dysprosium doped lithium magnesium borate glasses system has been investigated. Photon ...  Read More

Bohr Hamiltonian and interplay between γ-stable and γ-rigid collective motions with both Harmonic oscillation and Ring-shaped potentials for the γ-part.

Nahid Sohebi; Mahdi Eshghi; Majid Hamzavi; Mohsen Bigdeli

Volume 1, Issue 4 , October 2020, , Pages 55-64

  ‎In the present work‎, ‎the eigenvalue and eigenvector has been obtained by the Bohr Hamiltonian for even-even nuclei‎. ‎The competition between γ-stable and γ-rigid collective motions has been created in the presence of the rigidity parameter‎. ‎The β-part ...  Read More
