### [in2p3-00005978] Evidence for dynamical proton emission in peripheral Xe + Sn collisions at 50 MeV/u

24 novembre 2017

Relative angle correlation functions for mid-rapidity protons built up from 50 MeV/u Xe+Sn data recorded by the INDRA multidetector exhibit the characteristics of a non-equilibrated emission: they show an energy dependent anisotropy which cannot be accounted for by standard evaporation (...)

### [in2p3-00000038] Independence of fragment charge distributions of the size of heavy multifragmenting sources

24 novembre 2017

Charged product multiplicities and Z distributions were measured for single multifragmenting sources produced in collisions between Full-size image ( 1 K) and Full-size image ( 1 K) at the same available energy per nucleon. Z distributions are found identical for both reactions while fragment (...)

### [in2p3-00003421] Is reducibility in nuclear multifragmentation related to thermal scaling?

24 novembre 2017

Thermal scaling (Arrhenius law for an “elementary” probability p of binomial function) and reducibility in intermediate mass fragments (IMF's) production are examined for data of the reaction 129Xe+ natSn at 50 MeV/u. The study of the longitudinal velocities and of the average transverse energies (...)

3 juillet 2015

A previous analysis of the charge (Z) correlations in the $\Delta Z-$ plane for Xe+Sn central collisions at 32 MeV/u has shown an enhancement in the production of equally sized fragments (low $\Delta Z$) which was interpreted as an evidence for spinodal decomposition. However the signal is weak (...)
