Successful separation of neutron-skin oscillation

Successful separation of neutron-skin oscillation

important step toward clarification of mysteries of the universe

Jun 19, 2012

A group consisting of researchers from several universities in Japan, including Osaka University,  Kyoto University, Chiba University, succeeded in separating pygmy dipole resonance, the neutron-skin oscillation in zirconium 90 through high-precision measurement using proton beam. Detailed analysis of properties of pygmy dipole resonance will lead to the clarification of element synthesis at the time of supernova explosions and neutron stars. This will clarify the process of element synthesis in the universe and the size and hardness of neutron stars.
