Phys. Rev. Lett. 77, 3343–3346 (1996)Multi-keV Electron Generation in the Interaction of Intense Laser Pulses with Xe ClustersReceived 20 March 1996; published in the issue dated 14 October 1996 We have observed the production of multi-keV electrons through the irradiation of Xe clusters by an intense, near infrared, femtosecond laser pulse. We find the electron kinetic energy distribution consists of two features, a “warm” peak of between 0.1 and 1 keV and a “hot” peak of energy between 2 and 3 keV. These measurements are consistent with a picture of rapid electron collisional heating in the cluster and exhibit good agreement with numerical modeling of the electron energy distribution. © 1996 The American Physical Society URL:
