Temperature-excitation energy correlation measurements on several systems at different incident energies are discussed in the framework of the investigation on possible liquid-gas phase transition in nuclear matter. Results are compared to the presently available experimental caloric curves. Moreover theisotope and theexcited states temperatures, extracted from double ratios of isotope yields and population ratios of fragment unbound states, respectively, are compared. p ]The differences on the temperatures deduced from the two methods cannot be accounted for by the sequential feeding corrections. Instead, they seem to be related to the space-time evolution of the fragmentation process.
