M056200100004 AUTHOR (R.T.Jones,D.A.Jenkis,P.T.Debevec,P.D.Harty, M056200100005 J.E.Knott) M056200100006 REFERENCE (J,PR/C,43,2052,1991) M056200100007 INSTITUTE (1USAVIP,1USAUI) M056200100008 FACILITY (MICRT,1USAUI) The 100 % duty cycle accelerator M056200100009 MUSL-2 at Nuclear Physics Laboratory, University M056200100010 of Illinois. M056200100011 INC-SOURCE (TAGD) M056200100012 METHOD (COINC,EDE) M056200100013 DETECTOR (COIN,MWPC,SCIN) The large solid-angle LASA detector M056200100014 which consists of three concentric levels of wires M056200100015 multiwire proportional chambers, surrounded by two M056200100016 layers of plastic scintillators the inner of which M056200100017 was 3-mm thick dE-counter and the outer was 25 mm M056200100018 thick E-counter. M056200100019 SAMPLE The target gas, no additional details. M056200100020 COMMENT Results are presented from a 4He photodisintegration M056200100021 experiment performed with quasi-monochromatic photons M056200100022 using a large solid-angle detector. The M056200100023 target-bremsstrahlung technique gave a reliable M056200100024 absolute mormalization. In addition, an unambigious M056200100025 separation of the proton-triton channel from other M056200100026 photodisintegration channels was achieved.
