Direct measurement of the 4He(12C,16O) γ reaction cross section by detecting 16O recoils is in progress at Kyushu University tandem laboratory (KUTL). A long-time chopper (LTC) has been developed to reject backgrounds from 16O recoils which have time (energy) spread. In the measurement of 4He(12C,16O)γ cross section at Ecm = 2.4 MeV, LTC was found to reduce the backgrounds by about three orders of magnitude.
