Abstract

Astrophysical observables that are directly linked to nuclear physics inputs provide critical and stringent constraints on nucleosynthetic models. As ²⁶Al was the first specific radioactivity observed in the Galaxy, its origin has fascinated the nuclear astrophysics community for nearly forty years. Despite extensive research, the precise origins of ²⁶Al remain elusive. At present, the sum of all putative stellar contributions generally overestimates the ²⁶Al mass in the interstellar medium. Among the many reactions that influence the yield of ²⁶Al, radiative proton capture on its isomer ^26mAl is one of the least constrained reactions by experimental data. To this end, we developed a ²⁶Al isomeric beam and performed proton elastic scattering to search for low-spin states in ²⁷Si. The experimental method and the preliminary results of this on-going study will be presented.
