Uncovering the sign of nuclear deformations: Determination of prolate or oblate shape via low-energy $\alpha$ inelastic scattering

Shin Watanabe, Yoshiki Suzuki, Masaaki Kimura +1

Background: Understanding nuclear shape is a crucial problem in nuclear physics. In particular, determining the sign of quadrupole deformation, i.e., whether prolate or oblate, rem…
