Description
Formation of clusters in nuclei is a topic of great interest and fundamental importance throughout the history of nuclear physics. In light nuclei, development of cluster structure in states close to the corresponding decay threshold is a well established phenomenon, and significant progress has been made in search for novel cluster states in light nuclei, such as the α-condensate states (e.g Hoyle state) and the 3-α-linear-chain states in carbon isotopes. Cluster formation in dilute nuclear matter including the low-density surface of heavy nuclei has not been well studied experimentally, although it has been theoretically predicted. Such a non-homogeneous phase of nuclear matter plays an important role in understanding the structure of the neutron star and the supernovae explosion. In this talk, I will discuss the results of our recent experiment measuring the formation of alpha clusters at the surface of stable tin isotopes by using quasi-free (p,pα) reaction in normal kinematics with the high-resolution spectrometers of RCNP, Osaka University.
