Production of ²²⁹Th for medical applications: Excitation functions of low-energy protons on ²³²Th targets

NUCLEAR REACTIONS ²³²Th(p, n), (p, 3n), (p, 4n), (p, 5n)²²⁸Pa/²²⁹Pa/²³⁰Pa/²³²Pa, E=13-39.9 MeV; measured reaction products, Eγ, Iγ, σ(E) by activation method, and effective σ(E) for ²²⁹Th production using natural Th targets at HRIBF-ORNL facility. ²²⁹Pa(α), (EC); measured T_1/2, branching ratio for α and EC decay modes. Comparison with previous experimental values and theoretical predictions using PHITS and MCNP6 simulation codes.
