Does a nucleon many-body system stabilize by forming subsystem(s) in it? This is a long-standing question since the discovery of α-decay and has been investigated enthusiastically in nuclear physics.
We have started a new research project named the ONOKORO project where we comprehensively investigate clustering in medium-to-heavy mass nuclei using (p,pX) cluster knockout reactions under normal and inverse kinematics. The research is motivated by our previous study on alpha clustering in ^{112-124}Sn conducted at Research Center for Nuclear Physics, Osaka University [1].
The ONOKORO project will extend the study to d, t, ^3He, alpha clustering both in stable and unstable nuclei in the mass region of A=36—220. In the seminar, I will discuss the physics background, research plans at RIBF, RCNP, and HIMAC facilities, and status of detector development for the inverse kinematics knockout experiments.
