Abstract

Theoretical cross-sections are presented for Penning detachment of negatively-charged sodium clusters, receiving their detachment energy from Na*(3p0,2P). Two clusters are examined: Na- 7 and Na- 19. Classical trajectories describe the relative motion of the colliding species. Kohn-Sham density functional theory in local approximation, with exchange, correlation, and self-interaction corrections, and a spherical jellium potential, describe the electrons involved in the transition. In the range of collision energies from 0.1 to 10 eV/amu, the cross-sections for Penning detachment are approximately 10-13 cm2. This implies that Penning detachment may be an effective means to prepare neutral clusters from size-selected negative-ion clusters in the laboratory.
