Isoscalar giant resonance studies from a stored-beam experiment for the EXL project — •J.C. Zamora for the EXL E105 collaboration — Institut für Kernphysik, TU Darmstadt

The objective of the EXL project is the investigation of nuclear structure of EXotic nuclei, in Light-ion induced reactions, by using the future storage ring NESR at FAIR. In this project a universal detector system will provide high resolution and large solid angle coverage for kinematically complete measurements.
In a recent experiment at the present Experimental Storage Ring (ESR) at GSI, the collaboration has performed feasibility studies and first experiments by using a dedicated UHV capable detector setup. With this setup the interaction of a ⁵⁸Ni beam with an internal helium gas-jet target was investigated. The aim of the present experiment is to study the Isoscalar Giant Monopole Resonance (ISGMR) and the Isoscalar Giant Dipole Resonance (ISGDR) from inelastic alpha scattering. In this talk, simulation results and the current status of the data analysis will be discussed. This work is supported by BMBF (06DA9040I and 05P12RDFN8) and HIC for FAIR.
