M062600100008 INC-SOURCE (LCS) Laser-Compton scattering. M062600100009 METHOD (EXTB,SITA) M062600100010 SAMPLE 4HE (80%) and CH-4 (20%) gases mixture contained in M062600100011 time projection chamber (TPC) served as a detector. M062600100012 DETECTOR (TRD) The time projection chamber (TPC) containing the M062600100013 mixture of 4He (80%) and CH-4 (20%) gases provides M062600100014 the information of the track angles and energies of M062600100015 the charged particles produced in the reactions.

M062600100024 (20090811A) STATUS included into SUBENTs 002-005. M062600100025 COMMENT The 4He photodisintegration cross section has been M062600100026 measured in the energy region from 20 to 32 MeV. In M062600100027 the measurement a laser-compton-backscattered-gamma M062600100028 beam and a time projection chamber were employed. The M062600100029 result indicates the cross section increases up to 32 M062600100030 MeV, and there is no pronounced peak at around 25 MeV M062600100031 which has been previously adopted as the giant dipole M062600100032 resonance energy.
