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...
متن کاملIsospin in Fragment Production
Based on a general approach to binary systems we show that in low density region asymmetric nuclear matter (ANM) is unstable only against isoscalarlike fluctuations. The physical meaning of the thermodynamical chemical and mechanical instabilities is related to the inequality relations verified by the strength of interaction among different components. Relevance of these results in bulk and nec...
متن کاملIsospin Observables in Multifragmentation of Relativistic Projectiles
Multifragmentation is a universal phenomenon occurring when a large amount of energy is deposited in a nucleus. It was observed in high energy nuclear reactions induced by hadrons and heavy ions. It is believed to be a manifestation of the nuclear liquid-gas phase transition which is also expected to occur in crusts of neutron stars and in supernova explosions. This reaction offers a unique pos...
متن کاملSystematics 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...
متن کاملFluctuations 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 ...
