Abstract Fragments produced in the reactions of 69 MeV/nucleon 36Ar and 55 MeV/nucleon 40Ar on a Be target have been measured experimentally. The isotopic distributions from fragmentation reaction for both projectiles are reproduced by using a modified statistical abrasion-ablation model. Strong isospin effect exhibits in the isotopic distributions produced in 36Ar and 40Ar fragmentation. Experimental evidence is seen for the disappearance of the isospin effect in fragmentation reaction.
