CHARGE-STATE DISTRIBUTIONS OF SWIFT HEAVY-IONS BEHIND VARIOUS SOLID TARGETS S-THAN-OR-EQUAL-TO-Z(P)LESS-THAN-OR-EQUAL-TO-92,18 MEV U LESS-THAN-OR-EQUAL-TO-E-LESS-THAN-OR-EQUAL-TO-44 MEV/U)/

Noting the lack of and the increasing need for information concerning heavy ion stripping in the intermediate velocity regime, we have studi ed a large number of ion-target systems experimentally. We present exp erimental charge state distributions obtained at the GANIL accelerator for several projectiles (36 less than or equal to Z(p) less than or e qual to 92) with energies ranging from 18 MeV/u to 44 MeV/u, emerging from various target foils (4 less than or equal to Z(t) less than or e qual to 79) of natural isotopic composition. The target thicknesses (f rom 1 mu g/cm(2) up to several mg/cm(2)) are chosen to cover the pre- and post-charge-state equilibrium regimes. Charge state fractions, mea n charge state, charge distribution width, and emerging ion energy are tabulated for each of the 107 projectile-target element-target thickn ess combinations. We also present an improvement of the semi-empirical formulae proposed by Baron et al. to predict the mean charge states a nd the distribution widths at equilibrium. These formulae are compared with the available experimental data, (C) 1998 Academic Press.
