Electron transfer into the projectile continuum in near-relativistic ion-atom collisions

ORAL

Abstract

Fast ion-atom collisions permit in experiments on electron transfer into the projectile continuum to study the dynamics of ionisation and radiative and non-radiative capture close to threshold; this is an exceedingly sensitive test of theory. We have studied electron emission in forward direction in 2 systems with different projectile Compton profile, U$^{88+}$ + N$_{2}$ and Sn$^{47+}$ + N$_{2}$ , using the 0$^{0}$ electron spectrometer at the supersonic jet target of the ESR storage ring. We present first results for 90AMeV U$^{88+}$ und 300AMeV Sn$^{47+}$ + N$_{2}$ , for which coincidences between cusp electrons with v$_{e}\approx $v$_{Proj}$ and charge exchanged projectiles were measured.
