The inverse kinematics thick target scattering method (TTIK) was used to measure the Li-8 resonant elastic scattering on a He-4 target in order to investigate Li-8-alpha cluster configurations in excited states of B-12. A Li-8 beam at E-beam = 30.6 MeV, provided by the radioactive beam facility EXCYT of LNS in Catania, while passing through a thick Helium target decreases continuously its energy.

Abstract

The inverse kinematics thick target scattering method (TTIK) was used to measure the Li-8 resonant elastic scattering on a He-4 target in order to investigate Li-8-alpha cluster configurations in excited states of B-12. A Li-8 beam at E-beam = 30.6 MeV, provided by the radioactive beam facility EXCYT of LNS in Catania, while passing through a thick Helium target decreases continuously its energy. Thus, elastic scattering can be induced starting from the initial beam energy down to zero. Time of flight measurement between beam particles passing through a MCP detector and alpha-particles impinging on the Delta E stage of a Si telescope detector allows the discrimination of elastic scattering from nuclear reaction events, thus representing an improvement of the TTIK method. In this paper the used experimental technique and preliminary results will be described.
