Overview
This is the website for an international symposium on “High-resolution Spectroscopy and Tensor interactions” (HST15) that is to be held at Osaka University Nakanoshima Center from November 16th to 19th, 2015.
High-resolution spectroscopy of nuclear excited states and the nuclear spin-isospin responses is one of the fundamental research subjects in nuclear physics. The WS beam line at the RCNP Ring Cyclotron Facility, which is dedicated for the high-resolution spectroscopy together with the Grand Raiden spectrometer, has been providing important and distinctive data with unprecedented energy resolution since its completion in 2000. Observation of the fine structures of giant resonances, high-resolution measurement of the electric dipole response in heavy nuclei, determination of the neutron skin thickness and the nuclear equation of state, observation of spin-M1 strengths with high energy-resolution, and precise determination of the transition strengths, excitation energies, and single particle occupations are some of the highlights of the recent experimental works that provide new insights into the nuclear physics and the nuclear astrophysics.
Another important recent result from the Grand Raiden spectrometer is the possible signature of the effect of tensor interactions in the ground state of 16O via the observation of high-momentum nucleons. Although it had been known that the tensor interactions between nucleons is essential for binding nuclei, it was only recently that the effects of tensor interactions could be isolated experimentally, i.e. by observation of systematic shifts of single-particle orbitals and of high-momentum components of nucleons in nuclei. In addition, theoretical methods to include explicitly the tensor interactions have been developed at RCNP. It is recognized now that such explicit inclusion is indispensable for a better understanding of nuclear structures. More detailed experimental as well as theoretical studies are under progress at RCNP.
In conjunction with the recent exciting progresses on the occasion of the 15th anniversary of the WS beam line, we would like to hold a symposium for discussing the topics on the experimental and theoretical studies on nuclear excited states with high resolution spectroscopy and on the tensor interactions to pursue further advances in these fields. The symposium also aims at celebrating the retirement in the next March of Professor Y. Fujita, who has presented outstanding experimental data using the combination of the WS beam line and the Grand Raiden spectrometer.
