Large-angle L x-ray production by electrons

Experimental values are given for the yields and spectral energy purities of K x-ray beams emitted at 120° and 180° from various targets when bombared by 0.01- to 3.0-MeV electron beams. Yields and purities are determined for beryllium, carbon, aluminum, titanium, copper, silver, and gold targets as a function of the target thickness and target inclination angle.
