Phys. Rev. C 62, 064607 (2000) [10 pages]Nuclear isotope thermometry
S. R. Souza1, W. P. Tan2, R. Donangelo1, C. K. Gelbke2, W. G. Lynch2, and M. B. Tsang2 Received 4 April 2000; published 10 November 2000 We discuss different aspects which might influence temperatures deduced from experimental isotopic yields in the multifragmentation process. It is shown that fluctuations due to the finite size of the system and distortions due to the decay of hot primary fragments conspire to blur the temperature determination in multifragmentation reactions. These facts suggest that caloric curves obtained through isotope thermometers, which were taken as evidence for a first-order phase transition in nuclear matter, should be investigated very carefully. ©2000 The American Physical Society
