The inverse kinematics thick target scattering method (TTIK) has been used to study the Li-8 elastic scattering on He-4 in order to investigate Li-8-alpha cluster configurations in excited states of B-12. A Li-8 beam, provided by the radioactive beam facility EXCYT, at E-beam = 30.6 MeV, passing through helium thick target, continuosly decreases its energy inducing elastic scattering starting from the initial energy down to zero. Four Delta E-E double stage silicon detector telescopes were used to detect the recoil alpha-particles coming from the scattering. Event by event time measurement between beam particles passing through a MCP detector and alpha-particles impinging on Delta E stage allows elastic from inelastic events discrimination, thus representing an improvement of the TTIK method. In this paper the used experimental technique and some preliminary results will be briefly described.

Abstract
The inverse kinematics thick target scattering method (TTIK) has been used to study the Li-8 elastic scattering on He-4 in order to investigate Li-8-alpha cluster configurations in excited states of B-12. A Li-8 beam, provided by the radioactive beam facility EXCYT, at E-beam = 30.6 MeV, passing through helium thick target, continuosly decreases its energy inducing elastic scattering starting from the initial energy down to zero. Four Delta E-E double stage silicon detector telescopes were used to detect the recoil alpha-particles coming from the scattering. Event by event time measurement between beam particles passing through a MCP detector and alpha-particles impinging on Delta E stage allows elastic from inelastic events discrimination, thus representing an improvement of the TTIK method. In this paper the used experimental technique and some preliminary results will be briefly described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
