Scientific paper

A crossed beam method is used to measure the differential excitation cross section of O(1D) from the ground state at 20-eV electron impact level, covering an angular range from 30 to 150 deg. The total excitation cross section is 1.5 + or 0.7 x 10 to the -17th sq cm; this is in agreement with the theoretical value of 1.7 x 10 to the -17th sq cm, as calculated by Henry et al., (1969).
