Charge State Dependence of Stopping Power for Oxygen Ions Channeled in Silverher features observed in the energy spectra of the emergent ions are attributable to charge exchange in the crystal. Screening by Fermi electrons is expected to be the same for channeled and randomly penetrating ions. The results indicate that this screening is not effective in reducing the energy loss of the ion.

Stopping Power of Fast Channeled Protons in the Impact Parameter Treatment of Atomic Collisionsned quantitatively by the Bethe-Bloch formula for the average energy loss per unit path length or the electronic stopping power S. = - dE/dx. In a channeling situation, however, small impact parameters are avoided and the Bethe-Bloch theory no longer applies.

The Z1 Oscillations in Electronic Stoppingvelocities .. is obtained. The energy loss cross-section is proportional to the momentum transfer cross-section which depends upon the elastic scattering intensity in the target-projectile center-of-mass system. When applied to the scattering of electrons by incident atoms moving at velocities v. ~

Z1 3-Dependent Stopping Power and Range Contributionsmation on the projectile charge as (Z.e).. Recently , we extended this theory to include the (Z.e). dependence in a classical treatment which is equivalent to a second Born approximation. The Z.. contribution was calculated for the statistical model of the target atom in the Lenz-Jensen approxima

Depth Distribution of Damage Due to Ionizationfor the calculation of range and damage distributions. The calculation differs from Brice’s chiefly in that it allows for the transport of energy by recoils away from the primary projectile path. Like the damage distribution, it should be more accurate than Brice’s at low energies..It is found that

Charge State Dependence of Stopping Power for Oxygen Ions Channeled in Silverto preclude charge state equilibrium in crystals 1 μm thick. In fact, a large fraction of charges 8+ and 7+ passed through the crystal without any charge exchange. In this work we show that similar conditions obtain in Ag and we have measured the charge state dependence of the stopping power for 27.
