title: Photodetachment spectroscopy of PtBr4(2-): probing the Coulomb barrier of a doubly charged anion.
abstract: We probe the repulsive Coulomb barrier of the doubly charged anion PtBr(4) (2-) by photodetachment spectroscopy. The results are discussed in terms of models for the photoemission process, the excitation spectrum of PtBr(4) (2-), and calculations of the energy-dependent tunneling probability for various model potentials.
