摘要
A probe to extract the temperature(T_(iyr)) from intermediate-mass fragment has been proposed using the isobaric yield ratio(IYR) difference based on the modified Fisher model.By analyzing the isobaric cross section in the measured 140 A MeV^(40,48)Ca+~9Be reactions,the Tiyr can well fit the IYR difference for the large mass fragments.Because of the fragments are produced in different colliding regions,it is also suggested to select the fragments according to different mechanisms when using TIYR.
