摘要：

Experiments demonstrating the role of cluster formation on multiphoton-induced x-ray emission and the scaling of this phenomenon into the kilovolt range have been performed on Kr. For the Kr M shell, augmentation of Kr(n) formation leads to a large increase in Kr9+ (4p --> 3d) emission (approximately 100 angstrom) and the appearance of a strong band at approximately 90 angstrom. The observation of L-shell transitions (approximately 5-7.5 angstrom) demonstrates the scaling of this phenomenon into the kilovolt region and leads to the conclusion that the interaction produces direct inner-shell excitation with the emission of prompt x rays.
