Evaluating Cross Sections of Gallium Isotopes Production Using proton and deuteron Irradiation

Raghad S. Mohammed

Abstract


In the present work, the production of the cross sections of three Gallium isotopes: 35
66
31Ga
(t1
⁄2 = 9.4h, β+ = 4.2MeV), 36
67
31Ga
(t1
⁄2=3.2617d, EC=100%) and 37
68
31Ga
(t1
⁄2 = 68min,
Iβ+ = 89%) have been discussed. The Gallium isotopes have important applications in nuclear
medicine, particularly in Positron Emission Tomography (PET), Single Photon Emission Tomography
(SPET) imaging technique and used in tumors diagnosing. The production of irradiant
Ga 66
,
Ga 67
and
Ga 68
is made by irradiation of an enriched Zinc target using proton and deuteron
charged particles. Utilizing high cyclotron yield and low radionuclide impurities, the optimum
cyclotron energy range has been chosen for the production of Gallium isotopes. The cross
sections of (p,xn), (p,γ) and (d,xn) reactions for the production of Gallium isotopes have been
evaluated depending upon the empirical data taken from EXFOR library, which is belonging to
the International Atomic Energy Agency (IAEA). Also the yield for each reaction has been evaluated

Keywords
