Description

The 13N(α,p)16O reaction significantly influences the production of several radioactive isotopes (e.g. 56Ni, 44Ti and other iron group isotopes) during core-collapse supernovae, but substantial uncertainties remain in its reaction rate at astrophysically relevant temperatures. To address this, experimental data were collected using the CRIB facility at RIKEN over a broad range of centre-of-mass energies containing resonances that contribute to the reaction rate. The experiment achieved a 13N beam intensity of 1e6 particles per second with purity higher than 90%, providing high-quality data for analysis. This work will provide the cross-section and resonance data needed to reduce uncertainties in the reaction rate used in core-collapse supernova models.
