Measurements of the differential scattering cross sections of electron excited Na on Hg
Abstract
Crossed molecular beam techniques were used to measure the differential scattering cross sections of electron excited Na atoms on Hg atoms. Some Na atoms were excited up to the 3 2P3/2 F = 3 hyperfine state at the beam crossing position by a narrow band continuous wave laser. The difference between the scattering intensities with and without the laser beam yields the total differential scattering cross section Na 3P3/2 Hg. Mean values obtained in the 3 to 78 deg range (laboratory system) are given and compared with ground state Na(3S1/2) Hg scattering. An oscillatory energy dependent structure was measured at large angles greater than 30 deg. Quantum mechanics calculations can thus be performed from the mutual interaction NaP-states with Hg pseudopotential.
