“…Geissel et al [41,42] measured mean energy losses and straggling for several ions in gases and solids and energies from 0.5 -10 MeV/u. Although the main topic in that study has been the density effect in the mean energy loss, straggling data are reported in noble gases and nitrogen for Pb, Xe and Kr ions, several of which lie an order of magnitude above the Bohr value.…”

Abstract. Measurements have been performed on a time-of-flight setup at the Jyväskylä K130 cyclotron, aiming at energy-loss straggling of heavy ions in gases. Theoretical predictions based on recently developed theory as well as an empirical interpolation formula predict that straggling can be more than ten times higher than Bohr straggling in the MeV/u regime. Our measurements with up to 9.3 MeV/u Kr ions on He, N2, Ne and Kr targets confirm this feature. Our calculations show the relative contributions of linear straggling, bunching including packing, and charge exchange. Our results for stopping cross sections are compatible with values from the literature.

“…It is well known [18,19] that fast partially ionized projectiles are stopped by solids more effectively than by gases (i.e., the mass stopping power is larger for solids). A qualitatively similar gas-solid difference has also been found for slow nitrogen projectiles by Price et al [20].…”

“…A detailed study was carried out at the accelerator facility UNILAC/GSI (Darmstadt) using krypton, xenon, lead, and uranium projectiles in the energy range of 1 -10 MeV/u (Geissel et al, 1982). It was observed for the first time in experiments with 3.6-7.9 MeV/u uranium projectiles that the stopping power in gases is lower by up to about 20% than in solids.…”

The dependence of calcium ion subshell populations on the target density during the ion stopping process was analyzed using a five charge-state collisional-radiative model. The model, which consists of the ground and three excited states for every ion charge, was successfully compared with the experiment. The gas-solid difference of calcium ion charge state distribution has been numerically demonstrated. For Ca projectiles with energies of 4-11 MeV/u, the increase of the mean ion charge in solid target is explained by the increase of the total ionization rate and by suppression of the bound electron capture process at high densities of the stopping medium.
