  Yields of isotopically separated light fragments and residual nuclei produced
in p(1GeV)+A collisions have been analyzed. For both fragmentation and
spallation reactions isotopic scaling, i.e. factorization of the isotope
ratios, was observed. A generalized isoscaling for arbitrary combinations of
two systems has been demonstrated. The average isotopic temperature about 4 MeV
for fragmentation process was found.
