Abstract

The x-ray emission for 6- to 60-MeV iodine bombardment on thin Au targets was measured. Spectra, cross sections, and angular dependence of x-ray emission are reported. Special emphasis is placed on the noncharacteristic radiation formerly interpreted as $M$ radiation of a quasiatom with an effective atomic number of 132. The emission of this radiation is found to be nonisotropic strongly supporting the model of induced emission in the collision molecule.
