Abstract
The intensity of channeling radiation from natural diamonds of thickne sses of 13 to 55 mum has been investigated at electron energies of 5.2 and 9.0 MeV. The intensities scale with electron energy according to gamma5/2 and vary with the crystal thickness d as (1 - e(-lambdad)), f rom which the occupation length lambda-1 of the electronic states in t he crystal could be deduced. It amounts to 18 and 29 mum for 5.2 and 9 .0 MeV electrons, respectively. The strongest transition has an intens ity of 0.1 photon per e- per sr.
