(. gamma. ,p), (. gamma. ,pn), and (. gamma. ,pp) reactions on light nuclei in the. delta. (1232) resonance region

; ; ; ; ; ; ;
The cross sections of the reactions (..gamma..,p), (..gamma..,pn), and (..gamma..,pp) are measured for /sup 1/H, /sup 2/H, /sup 9/Be, /sup 12/C, and /sup 16/O in the ..delta..(1232) resonance region by use of a tagged photon beam. Protons emitted at theta/sub p/ = 30/sup 0/ are measured by a magnetic spectrometer, and the other neutrons or protons are measured by an array of scintillation counter hodoscopes. From the present experiment, it is concluded that the reactions, ..gamma..+''N''..-->..p+..pi.. and ..gamma..+''pn''..-->..p+n, contribute dominantly to the (..gamma..,p) reaction in this energy region, where ''N'' denotes the nucleon and ''pn'' denotes the pn system in the nucleus.
