Measurement of the ²³⁰Th(p, 2n)²²⁹Pa and ²³⁰Th(p, 3n)²²⁸Pa reaction cross sections from 14.1 to 16.9 MeV

NUCLEAR REACTIONS ²³⁰Th(p, 2n)²²⁹Pa, (p, 3n)²²⁸Pa, ²³²Th(p, n)²³²Pa, E=14.1, 14.4, 14.9, 15.7, 16.0, 16.9 MeV; measured Eγ, Iγ, production σ(E) using the activation method at the 10 MV tandem accelerator facility of Center for Accelerator Mass Spectrometry (CAMS) at Lawrence Livermore National Laboratory (LLNL). Comparison with the literature values, and with calculations using TENDL 2019 code. Relevance to production of ²²⁵Ac for medical applications.

RADIOACTIVITY ^228,229Pa(EC)[from ²³⁰Th(p, 2n), (p, 3n), E=14.1-16.9 MeV]; measured Eγ, Iγ, half-lives of decays of ²²⁸Pa and ²²⁹Pa. Comparison with the values in the ENSDF database.
