Systematics of fragment observables

Systematics of fragment observables

Multifragmentation is observed in many reaction types: light ion induced reactions at large incident energies (in the GeV region), central heavy ion collisions from 30 to 100 MeV/u, and peripheral heavy ion collisions between 30 and 1000 MeV/u or above. When nucleus-nucleus collisions are considered, another entrance channel parameter is the corresponding mass asymmetry. The first question whic...

Fluctuations of fragment observables

This contribution presents a review of our present theoretical as well as experimental knowledge of different fluctuation observables relevant to nuclear multifragmentation. The possible connection between the presence of a fluctuation peak and the occurrence of a phase transition or a critical phenomenon is critically analyzed. Many different phenomena can lead both to the creation and to the ...

Isospin observables from fragment energy spectra

The energy spectra of light charged particles and intermediate mass fragments from 112Sn+ 112Sn and 124Sn+ 124Sn collisions at an incident energy of E/A = 50 MeV have been measured with a large array of silicon strip detectors. We used charged-particle multiplicities detected in an array with nearly 4π coverage to select data from the central collision events. We study isospin observables analo...

Systematics of Global Observables in Cu+Cu and Au+Au Collisions at RHIC Energies

Charged particles produced in Cu+Cu collisions at √ sNN = 200 and 62.4 GeV have been measured in the PHOBOS experiment at RHIC. The comparison of the results for Cu+Cu and Au+Au for the most central collisions at the same energy reveals that the particle density per nucleon participant pair and the extended longitudinal scaling behavior are similar in both systems. This implies that for the mos...
