¹⁴¹Pr(α,x): New Cross-Section Data With Special Reference to ¹⁴⁰Nd Production for Medicine

Abstract

Cross sections for the ¹⁴¹Pr(α,x) ^144,143,141Pm, ^138mPr, ^{141cum,140cum}Nd, and ^139cumCe reactions were measured by the stacked foil technique at an alpha-particle range of 60 to 20 MeV. Most of the data were obtained for the first time. Experimental data were compared with earlier research and theoretical values from the TENDL-2021 database. Thick target yields of activation products were calculated. The reaction ¹⁴¹Pr(α,5n)¹⁴⁰Pm (9.2 s)→¹⁴⁰Nd was compared with other ¹⁴⁰Nd production routes.
