Isoscaling of spallation products from p(1 GeV)+A interactions


Isoscaling of spallation products from p(1 GeV)+A interactions

Andronenko, M. N.; Andronenko, L. N.; Neubert, W.; Seliverstov, D. M.

An analysis of experimental data consisting of isotopically resolved spallation products from 1 GeV proton-necleus interactions with targets from Fe to Cd 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 isotopic temperatures on the target mass was demonstrated for spallation products. An 'unified' isoscaling is proposed which takes into account different nucleonic compositions of the emitting sources. Modified isoscaling parameters are proposed and their physical meaning is discussed.
