Experimental study of charge-state distributions and photon emissions from beam-tilted-foil interactions

Relative spectral-line intensities of beam-foil-excited magnesium projectiles have been measured versus the projectile energy (100-900 keV) with carbon foils tilted 0^∘{}, 30^∘{}, and 45^∘{}. The photon intensities depend upon the foil tilt angle. Charge-state distributions measured for H⁺, C⁺, N⁺, O⁺, Na⁺, Mg⁺, S⁺, and Kr⁺ transmitted through carbon foils tilted 0^∘{}, 30^∘{}, and 45^∘{} (100-400 keV) were found not to be influenced by the tilt angle in contrast to the optical results. Charge-state distributions for C and S, which have not been reported earlier, are in agreement with a recently proposed independent-electron model for charge-state distributions and beam-foil populations.
