By employing the method of double ratios of isotope yields, the nuclea
r temperature parameters for the reactions of 30 MeV/u Ar-40 bombardin
g Ni-58, Ni-64 and In-115 targets, are extracted by yields of the frag
ments of 3 less than or equal to Z less than or equal to 8. The depend
ences of the apparent temperature on some observables are investigated
. The temperature values after correction for the side-feeding effects
are also deduced sind discussed.
