Determination of the He-He, Ne-Ne, Ar-Ar, and H $_{2}$ interaction potential by wave function imaging

arXiv:1802.02787 · doi:10.1103/PhysRevLett.121.083002

Abstract

We report on a direct method to measure the internuclear potential energy curve of diatomic systems. A COLTRIMS reaction microscope was used to measure the squares of the vibrational wave functions of H $_{2}$ , He $_{2}$ , Ne $_{2}$ , and Ar $_{2}$ . The SchrÃ¶dinger equation relates the curvature of the wave function to the potential V(R) and therefore offers a simple but elegant way to extract the shape of the potential.
