“…In this paper we extend the previous study [20] to a wider incident energy range, from 32 to 50 AMeV for central collisions of the Xe + Sn system measured with the 4π INDRA detector [22,23,24]. Excitation functions for the fragment excitation energy and the fraction of secondary emitted LCP correlated to the fragments will be shown.…”

Characteristics of the primary fragments produced in central collisions of129 Xe + nat Sn from 32 to 50 AMeV have been obtained. By using the correlation technique for the relative velocity between light charged particles (LCP) and fragments, we were able to extract the multiplicities and average kinetic energy of secondary evaporated LCP. We then reconstructed the size and excitation energy of the primary fragments. For each bombarding energy a constant value of the excitation energy per nucleon over the whole range of fragment charge has been found. This value saturates at 3 AMeV for beam energies 39 AMeV and above. The corresponding secondary evaporated LCP represent less than 40% of all produced particles and decreases down to 23% for 50 AMeV. The experimental characteristics of the primary fragments are compared to the predictions of statistical multifragmentation model (SMM) calculations. Reasonable agreement between the data and the calculation has been found for any given incident energy. However SMM fails to reproduce the trend of the excitation function of the primary fragment excitation energy and the amount of secondary evaporated LCP's.

“…The 4π multidetector INDRA, which is described in detail in [10,11], was thus used to reveal N/Z effects in heavy-ion reactions connected to the knowledge of symmetry energy entering the asymmetric nuclear equation of state [3,12,13]. In terms of detection INDRA possesses excellent performance: geometrical efficiency of 90%, rather low detection and identification thresholds (see Fig.…”

Abstract. The equation of state of asymmetric nuclear matter is still controversial, as predictions at subsaturation as well as above normal density widely diverge. We discuss several experimental results measured in heavy-ion collisions with the INDRA array in the incident energy range 5-80 A MeV. In particular an estimate of the density dependence of the symmetry energy is derived from isospin diffusion results compared with a transport code: the potential part of the symmetry energy linearly increases with the density. We demonstrate that isospin equilibrium is reached in mid-central collisions for the two reactions Ni+Au at 52 A MeV and Xe+Sn at 32 A MeV. New possible variables and an improved modelization to investigate symmetry energy are discussed.PACS. 2 5.70.Pq -2 4.60.Ky

“…This work aims to give a schematic guideline for measuring a selection of isospin observables with new-generation isospin-sensitive instruments, in comparison with former isospin-blind devices. In particular, within our simulation protocol, we focus on a forthcoming 4π detector, the four-π A and Z identification array (FAZIA, [23]), explicitly planned for measuring isospin observables and its isospin-blind ancestor, INDRA [24,25]. We focus only on these two detectors because they are well suited for representing two opposite situations.…”
