Geant4 Atomic Relaxation

open access: yesIEEE Transactions on Nuclear Science, 2005
The Low Energy Electromagnetic package of the Geant4 toolkit incorporates a component for the simulation of atomic relaxation of elements with atomic number between 6 and 100. This process is triggered by the creation of a vacancy in the atomic shell occupancy as a result of an incident particle interaction with an atom of the target material.

An iterating method to investigate the geometry of range modulation wheel in passive proton therapy [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2020
In the treatment of the  tumors using proton therapy, the synchrotron emits a monoenergetic beam that transports most of its energy in a special position after entering the target. There are two approaches to invading the entire tumor tissue.

Calculation of spectrum and neutron flux density in experimental channels of WWR-M reactor

open access: yesЯдерна фізика та енергетика, 2021
A program for calculating the spectra and densities of neutron fluxes in the experimental channels of the research reactor WWR-M was developed. To do this, the reactor core was modeled. Irradiation of neutron activation detectors was performed.
