TY  - JOUR
AB  - A measurement of the 23P0−23P2 fine structure interval in the helium has beeen made using the optical microwave atomic beam magnetic resonance technique. The result is 31.908 040 (20) GHz (0.6ppm), which establishes an internal consistency in measurements of the helium fine structure and verifies the theory to order α4Ry. When the theory is used together wit our experimental result we obtain a value for the fine structure constant α by α-1=137.03613(11) (0.8 ppm). © 1980, All rights reserved.
