Abstract
The density shift and broadening of the transition lines of antiprotonic he lium have been evaluated in the impact approximation using an interatomic p otential calculated ab initio with the symmetry-adapted perturbation theory . The results help to remove an uncertainty of up to 10 ppm in the laser sp ectroscopy data on antiprotonic helium and are of importance in experimenta l tests of bound state QED and CPT invariance.
