Scandium Kα and Kβ diagram, satellite and hypersatellite X-rays

Abstract
X-ray transitions from scandium due to proton, helium, and oxygen bombardment are reported. The oxygen +Sc spectrum displays the largest number of satellites including three hypersatellite transitions and in the He+Sc spectrum double electron transitions were observed. Hartree-Fock-Slater calculated energies were used to assign the transitions.
