HYPERFINE STRUCTURE SEPARATIONS IN GROUND STATE MULTIPLET OF STABLE CARBON ISOTOPE 13C

The hyperfine structure separations F= 5 2 ↔ 3 2 and 3 2 ↔ 1 2 in the 2p2 3P2 and 3P1 states, respectively, of 13C have been measured with the atomic beam magnetic resonance method. A combination of these data with other measurements yields -0.964(1) nm for the nuclear magnetic dipole moment of 11C. © 1969.
