- Title
Intra-cluster ionization and X-ray emission.

- Abstract
The interaction of high-intensity short-pulse laser radiation with atoms, bound in a cluster, releases electrons by field ionization. These electrons are accelerated inside the cluster to give rise to a collisional inner-shell ionization. The excited ions can produce prompt and possibly amplified X-ray s. This model, developed on the basis of experimental results by Rhodes and coworkers [9,10] is analysed in detail. The calculations predict that the generation of excited states inside the cluster is in principle possible, but the effectivity is relatively small. However, taking into account the multiple pass of the (oscillating) electron in the cluster and – in extension to [9,10] – the production of excited ion states in a recombining scheme, an attractive prompt and, in addition, short-time amplified X-ray emission is to be expected. In a first approximation the time behaviour will be discussed specifically for the rare-gas (Ar, Kr, Xe) clusters and C[sub 60] .
