We have developed a model for the generation of K{sub α} radiation and the formation of hot electrons under vacuum heating by a femtosecond laser pulse near the surface of spherical clusters. The simulation results correspond to measurements at a cluster diameter of less than or of the order of the wavelength for the cases of p-polarised laser radiation and radiation incident along the normal to the surface. We discuss a significant decrease in the conversion of the laser energy into the energy of K{sub α} emission with decreasing wavelength from 1.24 to 0.4 μm, which is observed at an intensity of 2 × 10{sup 17} W cm{sup -2}.
