The Hyperfine Structure and Nuclear Moments of the Stable Chlorine Isotopes

Abstract
The hyperfine structure of the P322 ground states of Cl35 and Cl37 is investigated by the atomic beam magnetic resonance method. Values of the magnetic dipole interaction constant, a, and the electric quadrupole interaction constant b are found to be a35=205.288±0.010 Mc/sec., a37=170.686±0.010 Mc/sec., b35=55.347±0.020 Mc/sec., b37=43.256±0.020 Mc/sec.
