“…Most of the experimental [2 to 10] and theoretical [11 to 13] works have chosen H 2 and H 3 as molecular projectiles because they have the simplest structure where vicinage effects can be observed: H 2 is a molecule with a mean internuclear distance equal to 2.4 a.u. [14], and H 3 is an equilateral triangular molecule with sides of 1.9 a.u. [15].…”

The electronic stopping power of amorphous carbon targets for H2+ and H2+ molecular beams has been analysed within the framework of the dielectric formalism. Coulomb explosion between the partners of the molecule has been taken into account to evaluate the average stopping power ratio during the dwell time. The charge state of the fragments is assumed fully stripped. Analysis and comparison of the calculated stopping power ratio with experimental data show a reasonable agreement.

This work presents the results of computer simulations for the energy spectra of original versus recombined H 2 + molecular ions transmitted through thin amorphous carbon foils, for a broad range of incident energies. A detailed description of the projectile motion through the target has been done, including nuclear scattering and Coulomb repulsion as well as electronic self-retarding and wake forces; the two latter are calculated in the dielectric formalism framework. Differences in the energy spectra of recombined and original transmitted H 2 + molecular ions clearly appear in the simulations, in agreement with the available experimental data. Our simulation code also differentiates the contributions due to original and to recombined H 2 + molecular ions when the energy spectra contain both contributions, a feature that could be used for experimental purposes in estimating the ratio between the number of original and recombined H 2 + molecular ions transmitted through thin foils.

“…This effect is a manifestation of the quantum nature of the energy transfers as the projectile slows down during its passage through the target. Several experiments were performed in the 1960's to investigate in detail the Lewis effect [2][3][4][5][6][7][8]. The size of the Lewis peak was observed to depend strongly on such factors as the purity of the target (especially on layers of surface contamination), the beam energy spread, and the beam energy stability.…”

“…In subsequent work [2][3][4][5][6][7][8] the collision spectrum co(Q) was assumed to arise predominantly from collisions with electrons in the target medium and to follow a 1/Q 2 law; however, this law is only valid for free electrons. To correct somewhat for this fact, the spectrum co(Q) was cut at a minimum energy transfer Qmin, where the value of Qmin was obtained from a fit to the data.…”

Recent experiments measuring the thick-target yield curve of narrow resonances in (p, ~/) reactions on 23Na, 26Mg and 27A1 nuclei clearly show the Lewis effect. We have studied this effect theoretically on the basis of a Monte Carlo simulation of the nuclear and electronic energy loss curve in the target. We are able to reproduce the experimental data qualitatively. We discuss possible implications of precision measurements of the Lewis effect.
