“…Similar observation has also been made [24] in reactions between 32S and various targets where no preequilibrium emission was required to account for the data. The present interpretation departs also from that where an intermediate rapidity source is generally required to reproduce the data [2,3,[25][26][27][28][29][30] and which implies a more violent interaction between projectile and target and the existence of a more highly excited zone than in the present reaction.…”

The light charged particles emitted in the 4~ reaction performed at 14.6, 19.6 and 35 MeV/nucleon have been studied inclusively. The energy spectra have been analysed in terms of preequilibrium emission, moving source and coalescence models. A complete coherence between the present data and those obtained separately from heavy fragment studies is achieved. These data are consistent with the onset of projectile fragmentation between 20 and 35 MeV/nucleon correlated with the formation of a highly excited region of the nuclear system inducing light particle emission. The other sources of light particles can be interpreted as statistical and sequential decay of the quasi projectile.

“…the slopes of the energy spectra, as a result of the transfer of angular momentum. For comparison, values of rm/c~-O.08 were needed to describe the energy and angular distributions of light particles in reactions of ~4N and 160 with Au at similar bombarding energies per nucleon [31,32]. The azimuthal angular correlations of pairs of lithium fragments in the reaction 4~ + Au at E/A = 27 MeV habe been fitted by assuming an average angular momentum of (g)= 80 h [29].…”

Abstract. Inclusive cross sections of intermediate mass fragments from the reaction 84Kr-~-I97Au at ElA = 35 MeV were measured over the range 8 ~ < Olab < 70 ~ with a low detection threshold. A moving-source parameterization was used to fit the double-differential cross sections. The integrated cross section for fragment production exceeds the total reaction cross section thus indicating a large probability for multi-fragment processes. The deduced large temperature parameters can be explained by assuming emission from a rotating source. From the comparison to reactions with 12C and 4~ projectiles at E/A = 30 MeV a systematics of inclusive fragment production as a function of the projectile mass is obtained. 25.70.Lm; 25.70.Mn; 25.70.Pq to 3.6 GeV, they seem to be associated with the larger IMF multiplicities [ 11 ]. PACS:In this work the systematics of the inclusive IMF production is extended to heavier projectiles. We report cross sections for the reaction at E/A = 35 MeV which were measured with a low detection threshold over a large range of angles. The atomic number of the observed fragments extends from Z = 3 up to Z = 36. Fragments up to Z = 24 were included in the moving-source analysis of the measured double-differential cross sections. By comparing to data for the reactions 12C "q-197Au[12] and 4~ + !97Au [6], both at E/A = 30 MeV, the role of the projectile mass in this energy regime is investigated. This measurement also complements the numerous exclusive studies of the 84Kr + 197Au reaction which were conducted in order to discern the dominant mechanisms of fragment production [13][14][15][16][17].

“…Summary of temperature measurements Fig.11 shows an overall picture provided by the present data using different thermometers. The kinetic temperatures extracted from fitting the charged particle energy spectra with an intermediate rapidity source exhibit a smooth trend over a wide range of incident energies from a few MeV to nearly 1GeV per nucleons [74]. The open diamond points shown in Fig.11 are the proton kinetic temperatures extracted from [74] over a narrow range of incident energies for comparison purposes.…”

The equation of state of nuclear matter suggests that at suitable beam energies the disassembling hot system formed in heavy ion collisions will pass through a liquid-gas coexistence region. Searching for the signatures of the phase transition has been a very important focal point of experimental endeavours in heavy-ion collisions, in the last fifteen years. Simultaneously theoretical models have been developed to provide information about the equation of state and reaction mechanisms consistent with the experimental observables.
