Abstract

The A/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at SIS. A stable beam of {sup 124}Sn and radioactive beams of {sup 124}La and {sup 107}Sn at 600 MeV per nucleon have been used in order to explore a wide range of isotopic compositions. Chemical freeze-out temperatures are found to be nearly invariant with respect to the A/Z of the produced spectator sources, consistent with predictions for expanded systems. Small Coulomb effects ({delta}T{approx_equal}0.6 MeV) appear for residue production near the onset of multifragmentation.

Isospin-dependent multifragmentation of relativistic projectiles

Journal Article Ogul, R ; Department of Physics, University of Selcuk, TR-42079 Konya ; Botvina, A S ; ... - Physical Review. C, Nuclear Physics

The N/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at the GSI Schwerionen Synchrotron (SIS). Stable and radioactive Sn and La beams with an incident energy of 600 MeV per nucleon have been used in order to explore a wide range of isotopic compositions. For the interpretation of the data, calculations with the statistical multifragmentation model for a properly chosen ensemble of excited sources were performed. The parameters of the ensemble, representing the variety of excited spectator nuclei expected in a participant-spectator scenario, are determined empirically by searching for an optimum reproductionmore »« less

Effect of nucleon exchange on projectile multifragmentation in the reactions of {sup 28}Si+{sup 112}Sn and {sup 124}Sn at 30 and 50 MeV/nucleon

Journal Article Veselsky, M ; Ibbotson, R W ; Laforest, R ; ... - Physical Review C

The multifragmentation of quasiprojectiles was studied in the reactions of a {sup 28}Si beam with {sup 112}Sn and {sup 124}Sn targets at projectile energies of 30 and 50 MeV/nucleon. The quasiprojectile observables were reconstructed using isotopically identified charged particles with Z{sub f}{<=}5 detected at forward angles. The nucleon exchange between projectile and target was investigated using the isospin and the excitation energy of the reconstructed quasiprojectile. For events with total reconstructed charge equal to the charge of the beam (Z{sub tot}=14), the influence of the beam energy and target isospin on the neutron transfer was studied in detail.

The decline of multifragmentation in {sup 197}Au + {sup 197}Au collisions at E/A = 100, 250 and 400 MeV

Journal Article Tsang, M B - Bulletin of the American Physical Society

Multifragmentation events have been measured in 4{pi} coverage for {sup 197}Au collisions at E/A = 100, 250 and 400 MeV using the Miniball/Wall, the Catania Silicon-CsI array and the Aladin Spectrometer. For E/A = 250 MeV and 400 MeV, there is monotonic relation between charge particle multiplicities, N{sub c} and bound charge particles from the projectile spectator, Z{sub bound}. At E/A = 100 MeV, the number of intermediate mass fragments (Z>3) produced increases monotonically with N{sub c} reaching values close to 10 fragments for the most central collisions. As the incident energy is increased, however, the multiplicity of fragments producedmore »« less
Experimental studies of N/Z equilibration in peripheral collisions using fragment yield ratios

Journal Article Keksis, A L ; May, L W ; Kohley, Z ; ... - Physical Review. C, Nuclear Physics

Peripheral collisions of {sup 40}Ca and {sup 48}Ca projectiles at 32 MeV/nucleon on {sup 112}Sn and {sup 124}Sn targets were studied in this work. The fragments of the projectile-like source (quasiprojectile) were collected with a charged-particle multidetector array. The average value of the neutron-to-proton ratio N/Z of the quasiprojectiles formed in the reactions was determined with two approaches. The first is a direct reconstruction approach using isotopically resolved fragments and is hindered by undetected neutrons leading to lower N/Z values. The second approach, based on the assumption of early fragment formation, employs yield ratios of fragment isobars and is notmore »« less

Dynamical aspects of multifragmentation

Conference Lindenstruth, V ; Pochodzalla, J ; Adloff, J C ; ...

The decay channel of excited nuclear matter into multiple complex fragments is still not thoroughly understood. Different scenarios are discussed, for example, the role of sequential decay of multiple binary breakups. Condensation processes in an expanded nucleus are reviewed. The latter is especially interesting due to its link to a nuclear liquid-gas phase transition. More recently it was proposed that the fragmentation process could be introduced by shape instabilities arising from surface fluctuations. To understand the decay mechanism it is very important to get an estimate of the size of the decaying source and the relative emission time of themore »« less
