A STUDY ON THE CALCULATIONS OF CROSS–SECTIONS FOR 66,67Ga AND 75Se RADIONUCLIDES PRODUCTION REACTIONS VIA 3He PARTICLES

Abstract

The intend of this paper is to study on different production routes of medical 66,67 Ga and 75 Se radionuclides used in cancer diagnostic. Both 66,67 Ga and 75 Se are the most well-known radionuclides used in diagnostics of malignant and benign tumors also brain studies and scintigraphy scanning. For this purpose, production cross-section calculations of medical 66,67 Ga and 75 Se radionuclides have been calculated for 64 Zn( 3 He,p) 66 Ga, 65 Cu( 3 He,2n) 66 Ga, 65 Cu( 3 He,n) 67 Ga, 66 Zn( 3 He,n+p) 67 Ga, 69 Ga( 3 He,n+α) 67 Ga, 76 Se( 3 He,α) 75 Se, 77 Se( 3 He,n+α) 75 Se reactions. In the calculations, TALYS 1.8 and ALICE/ASH computer codes have been used. The models which have been employed within the calculations are Two Component Exciton and Equilibrium of TALYS 1.8 and Hybrid and Geometry Dependent Hybrid of ALICE/ASH. The results obtained from the calculations for each reaction have been compared with other calculation results and previously recorded experimental values collected from the Experimental Nuclear Reaction Data (EXFOR) library.

Calculation of Mass Attenuation Coefficients for Pedicle Screw by Theoretical and Monte Carlo Simulation Methods

“…The XCOM software is possible to obtain photon cross-section data for a single element, compound, or mixture. It was used to calculate theoretical values of the halfvalue layer and mass attenuation coefficients (µm) of the samples for γ-rays at photon energies of 60 -250 keV [36]. In nuclear physics, numerous computer codes, based on analytical approximations [30][31][32][33][34][35][36] and MC techniques [37][38][39][40][41][42][43], are widely used by researchers.…”

MC techniques can be used in the solution of probabilistic processes such as radiation transport as well as in a complex integral calculation that is not practical to solve [44].…”

A Theoretical Study on the Production Cross–Section Calculations for 24Na Medical Isotope

“…The models, which are most compatible with the experimental data, were selected by the relative variance analyses (Kurenkov et al, 1999) method. There are many studies that contributed to the literature by examining the cross-section calculations of radioisotopes via various theoretical models and calculation tools (Kaplan et al, 2020;Özdoğan et al, 2020a;Şekerci et al, 2020c;Şekerci, 2020b;Karaman et al, 2020;Sarpün et al, 2019;Özdoğan et al, 2019b;Özdoğan et al, 2019c).…”
