CHARGE EXCHANGE FOR H+ TO H- IN POTASSIUM OR CESIUM VAPOR IN ENERGY RANGE 0,5 TO 2 KEV

For sources for polarized ions at a tandem accelerator the charge changing process from H+ to H- in potassium and cesium metallic vapour is very favourable. The charge changing yield in potassium amounts to 10% at a proton energy of 0.5-1.5 keV, and to 15% in cesium at a proton energy of 0.5 keV. © 1968 Springer-Verlag.
