Abstract.
An analysis of experimental yields concerning isotopically resolved spallation products from 1GeV-proton nucleus interactions with targets from Fe to Cs is presented. It was found that the yield ratios of isotopes classified by the difference of the neutron numbers are compatible with relations derived in the grand-canonical approach. The independence of isotope temperatures from the target mass was demonstrated for spallation products. The spallation residues exhibit isoscaling behaviour. The high sensitivity of the isoscaling parameters to the nucleonic composition (N/Z) of the disassembling nuclei is analysed. A unified isoscaling for a common description of similar reactions is discussed.
