Nuclear Physics with Light Ion Beams

Results by the RCNP Ring Cyclotron

Abstract

A nucleus is a many-body quantum system consisting of protons and neutrons with spin=1/2 and isospin=1/2. The structure of atomic nuclei has been investigated with a variety of of probes. It was found that the atomic nucleus is a quite unique system where independent particle and collective motions coexist. Today, in order to better understand the atomic nucleus, it becomes more important to clarify microscopic structres produced by the nucleons near the surface in search of various collective motions with large amplitudes and to investigate modifications of nucleon properties in the nuclear medium.
Nuclei are sensitive detectors in such interdisciplinary fields as cosmophysics and astrophysics. Information on nuclear structures is indispensable to determine the efficiency of detectors. In this report, we describe research activities on these subjects performed with the RCNP Ring Cyclotron.
