Abstract

Physical Sciences Physics Physics, Atomic, Molecular & Chemical Science & Technology
The symmetry of atomic wave functions is broken by the quadrupolar component of the van der Waals interaction between the atom and a planar surface. This results into a coupling able to mix levels of same parity such as P-3(0) and P-3(2) metastable levels of heavy rare gas atoms. The P-3(0)-P-3(2) transition in Ar and Kr has been evidenced in a time-of-flight experiment using as a surface the edge of a copper slit.
