Abstract
We report the first measurement of the kinetic energy release distributions of multiply charged oxygen ions produced in collisions of O2 molecules with 5.9 MeV/amu Xe18+ and Xe43+ ions. The slow Oq+ ions generated in the collision are detected in coincidence by a time- and position sensitive multi- particle detector. An analysis of correlated momenta of molecular fragments provides the kinetic energy release distribution for various reaction pairs O2 → Oq1+Oq2+ with a total charge up to q = q1 + q2 = 11. The position of the maximum and the width of the distributions are well described by the recently suggested Average Bunch Statistical (ABS) model.
