| Abstract: | The complete finestructure beat frequency patterns ofn 3 P states of4He I (n=3–7) are measured by observation of zero field quantum beats using the beam-foil technique. The results provide a new experimental value for the 73 P 2–73 P o separation, confirm the beat amplitude ratios to be in accord with theory and allow comparison with the results of other techniques. |
