Abstract
Calculations of the photoionization cross sections of excited nl states of cesium for n\ensuremath{\le}9 and l\ensuremath{\le}3 have been carried out within the framework of the central-field model. In addition, oscillator strengths for discrete transitions among these excited states have been obtained. The oscillator-strength distributions are presented and analyzed and the prominent zeros in the matrix elements for excited states are discussed in detail. Procedures and pitfalls in interpolation and extrapolation of discrete oscillator strengths are discussed, and the photoelectron angular distributions from these excited states are also presented.
