Charged state distributions of swift heavy ions behind various solid targets (36 {le} Z{sub p} {le} 92, 18 MeV/u {le} E {le} 44 MeV/u)
- CEA-CNRS, Caen (France)
Noting the lack of and the increasing need for information concerning heavy ion stripping in the intermediate velocity regime, the authors have studied a large number of ion-target systems experimentally. They present experimental charge state distributions obtained at the GANIL accelerator for several projectiles (36 {le} Z{sub p} {le} 92) with energies ranging from 18 MeV/u to 44 MeV/u, emerging from various target foils (4 {le} Z{sub t} {le} 79) of natural isotopic composition. The target thicknesses (from 1 {micro}g/cm{sup 2} up to several mg/cm{sup 2}) are chosen to cover the pre- and post-charge-state equilibrium regimes. Charge state fractions, mean charge state, charge distribution width, and emerging ion energy are tabulated for each of the 107 projectile-target element-target thickness combinations. They also present an improvement of the semi-empirical formulae proposed by Baron et al. to predict the mean charge states and the distribution widths at equilibrium. These formulae are compared with the available experimental data.
