Abstract

Radiative double-electron capture, which can be considered the inverse of double photoionization, has been investigated for 2.11 MeV/u F9+ and F8+ projectiles colliding with the two-dimensional target single-layer graphene. Preliminary results for the cross sections are obtained and presented and compared with our previous measurements for the one-dimensional gas targets N2 and Ne, with the three-dimensional target thin-foil C, and with the most accurate theoretical results that currently exist. The graphene results reported here are reasonable when compared with the F9++N2, Ne results given the thicknesses of the respective targets, being larger by about a factor of four.
