摘要：

Photoelectron angular distributions for resonantly enhanced three-photon ionization (2+1) of cesium via the ns (n=8e"12) states have been measured. The asymmetry parameter is found to vary from +1.2 for the 8s state to -0.5 for the 12s state. These results provide the first clear experimental evidence for relativistic (spin-orbit) effects on the photoelectron angular distribution for an alkali-metal atom. © 1990 The American Physical Society.
