7 Mar 2000 | Journal: | Phys.Lett. B497 (2001) 1-7 | Subject: | nucl-ex | Affiliation: | Cyclotron Institute, Texas A&M University, College Station, Texas | Abstract: | A dependence of the isobaric ratio Y(3H)/Y(3He) on the N/Z ratio of the reconstructed quasiprojectile for the reaction of 28Si beam with 112,124Sn targets at two different projectile energies 30 and 50 MeV/nucleon is presented. We demonstrate a linear dependence of ln(Y(3H)/Y(3He)) on the quasiprojectile N/Z ratio and show the dependence of the slope on reconstructed excitation energy of the quasiprojectile. We relate this slope dependence at a given excitation energy to the temperature of the fragmenting system. Using the model assumptions of the statistical multifragmentation model, a method of temperature determination is proposed. A caloric curve is constructed and compared to the result of double isotope ratio method for the same set of data and to the results of other studies. | Source: | arXiv, nucl-ex/0003004 | Services: | Forum | Review | PDF | Favorites |
