We will present an experimental plan to measure proton resonant elastic scattering with a thick target in inverse kinematics with a novel beam of isomeric Al-26 to be produced with CRIB at RIBF of RIKEN Nishina Center. The steady-state galactic abundance of the Al-26 radionuclide provides a unique window to the ongoing nucleosynthesis in the MIlky Way, as its decay along the galactic plane has been directry observed by astronomical telescopes. Despite a lot of efforts over the past four decades, the precise site of galactic Al-26 is poorly figured out. The experiment aims to search for strong proton resonances with low spin-parity in Si-27 using an isomeric beam of isomeric Al-26.
