The reaction products from d-7Li were studied using a 150 keV deuteron beam from SAMES J-15 accelerator at Çekmece Nuclear Research and Training Centre (ÇNAEM). The target was obtained by evaporating natural LiF (800μg/cm2) onto Aluminium backing (1500μg/cm2). Two silicon surface barrier detectors (SSB) were chosen in order to detect all the alpha-particles produced in the reaction and they were placed on the opposite side respect to the beam. The alpha-alpha coincidence technique was employed and energy signals from SSB#2 detector placed on 83.50 are gated with 6.7 - 8.2 MeV interval of energy signals from SSB#1 placed on 900 . Coincidence spectra obtained were corrected for the energy loss in the target. The coincidence spectra were then unfolded and alpha lines belonging to the ground and first excited states of 5He were then identified.
