Peripheral interactions of the 22 Ne + 93 Nb system at 30 A· MeV incident energy have been investigated using the forward 48 CsI scintillators of the AMPHORA multidetector array for the detection of light charged particles at forward angles. In addi

Mechanisms of non-equilibrium light-particle emission in 32S + Ag reactions at 30 A · MeV

Publikováno v: Nuclear Physics A. 539:316-350

Energy spectra of light charged particles (Z = 1,2) observed at θLP = 5°−150° in coincidence with fragments of Z = 5–14 at θF = ±9° are examined. The fragment-energy spectra show two components, one with a projectile-like velocity and anoth

Publikováno v: Physical Review Letters. 47:639-642

Light-particle emission in the fusion reactions in the system /sup 14/N+/sup 27/Al at 100 MeV has been studied with use of coincident techniques. Comparison of the data with a statistical model accounts for the energy and angular distributions of the

α-Emission temperatures, coulomb instabilities and nuclear cracking

Publikováno v: Physics Letters B. 196:429-433

The α-emission temperatures of medium mass nuclei with masses near 140, determined at excitation energies from 2 to 4.3 MeV/nucleon, suggest a rapid increase in the heat capacity of the composite system consistent with model predictions of the onset

Physics Letters B, Elsevier, 1984, 137, pp.318-322

We have investigated the fragmentation mechanism associated with the emission of light particles in the reaction 14 N + 27 Al at 30 MeV/amu in singles and in coincidence measurements. We find that the multiplicity for such particles is approximativel

Temperatures and excitation energies of hot nuclei in the reactions ofS32+Ag andO16+Ag at 30 MeV/nucleon

For the reactions of 30 MeV/nucleon /sup 16/O and /sup 32/S with Ag, singles and coincidence measurements have been made for heavy residues, fragments (3less than or equal tozless than or equal to14), and light charged particles (zless than or equal

Local equilibration and diffusive phenomena in40Ar+27Al and14N+27Al heavy ion reactions

Publikováno v: Zeitschrift f�r Physik A Atoms and Nuclei. 297:317-321

Extensive analysis of the energy dissipation and nucleon exchange has been done with heavier systems. Here we choose the two light systems40Ar+27Al (E lab=340 MeV) and14N+27Al (E lab=100 MeV) in order to study the correlation of the energy dissipatio

The observation of projectile-like fragments with an energy corresponding to the beam velocity turns out to be mostly explained by the break-up of the projectile, the break-up of the ejectile formed by transfer and the decay of the excited projectile

Nucleon transfer calculation in reactions induced by12C to22Ne ions

Autor: N. Chevarier, A. Demeyer, A. Chevarier, R. Billerey, C. Cerruti

Publikováno v: Zeitschrift für Physik A Atoms and Nuclei. 285:389-395

A classical-statistical model is presented here in order to predict the isotopic production in light heavy ion reactions. The dynamical approach includes a nucleon exchange term. Such transfer is made possible through a window and a simple gas theory
