Establishing the ${}^{40}$Ca$(p,p\alpha )$ reaction at 392 MeV under quasi-free scattering conditions

Riku Matsumura, Junki Tanaka, Kazuki Yoshida +80

The $(p,p\alpha )$ reaction offers a direct means to probe preformed $\alpha$-cluster structures in nuclei under quasi-free scattering conditions. Previous studies around 100 MeV provided va…
