Production of Protactinium-229 via Deuteron Irradiation of Thorium-232

²²⁵Ac [Actinium-225] is a promising radionuclide for targeted alpha therapy of cancer. ²²⁹Pa can lead to the production of ²²⁹Th [Thorium-229] and ²²⁵Ac [Actinium-225]. Deuteron bombardment on natural thorium targets has been investigated to measure cross sections of protactinium isotopes. In this work, ²²⁹Pa [Protactinium-229] excitation function was measured via deuteron energies up to 50 MeV [Mega electron volt] of thin thorium foils. The irradiation took place at Lawrence Berkeley National Laboratory’s (LBNL) 88-Inch Cyclotron. The target processing and analysis were performed at Oak Ridge National Laboratory (ORNL). The target consisted of 4 thin foils (~17 mg/cm² [milligrams per square centimeter]) in a stacked-target configuration, and were irradiated with 1 μA [microampere] for approximately 11 continuous hours. Column chromatography techniques had been implemented to observe ²²⁹Pa due to its weak γ-rays [gamma-rays]. The primary motivation of this work is to quantify the production routes of ²²⁹Th. ²³²Th(d,5n)²²⁹Pa reaction cross sections are reported for the first time. The peak of the excitation function of ²³²Th(d,5n)²²⁹Pa at 121.9 ± 12.7 mb [millibarns] occurs at E_d = 35.2 MeV. The production cross sections of ²³²Th(d,xn)^{228,230,232,233}Pa reactions, where x = 1,2,4, and 6, are also reported. Other measured cross sections are in excellent agreement with published data in the literature. The experimental cross sections were compared with transport code using Particle and Heavy Ion Transport code System (PHITS) and exhibited good agreement.
