Sažetak
The 8Li elastic scattering on a 4He gas target was studied by means of the Inverse Kinematics Thick Target scattering method (TTIK) in order to investigate cluster configurations in excited states of 12B. A 8Li beam, at Ec.m.= 10.2 MeV, was provided by the EXCYT radioactive beam facility at Catania. The beam, while passing through the helium thick target decreases its energy, thus exploring the 8Li-alpha center-of-mass energy range 2.7 MeV <= Ec.m.<= 9.6 MeV. Four DeltaE-E silicon detector telescopes were used to detect the recoiling alpha particles. The time interval between the 8Li passing through a micro-channel plate foil, placed at the entrance of the chamber, and the detection of the alpha particles by the DeltaE detectors was also measured. The time measurement allows to disentangle elastic from reactions events, otherwise impossible from energy measurements. This can be considered as an improvement of the TTIK method. In this paper the used experimental technique and the obtained preliminary results will be presented.
