Photon-induced fragmentation in 27Al and 32S by 1-GeV bremsstrahlung

Polyethylene, water, lithium fluoride, aluminium, and sulfur targets have been irradiated with 1-GeV bremsstrahlung beams at the Frascati electron synchrotron and the yields of some spallation products from ²⁷Al and ³²S and of ¹¹C and ⁷Be from ¹²C, ¹⁶O, ¹⁹F, ²⁷Al, and ³²S have been measured by the induced-activity and radiochemical methods. Evidence has been deduced for fragmentation from the mass-yield distribution of the photoproduced nuclides in ²⁷Al and ³²S.
