Abstract
AN atomic beam apparatus using magnetic resonance1 has been built and used for finding the spin of sodium-24. The focusing magnets and the radio-frequency section are similar to those used by Davies2 for studying the spin and hyperfine structure of sodium-22. The intensity of the sodium-24 beam was found by collecting on a target and afterwards measuring the activity of the sodium-24 deposited. The sodium-24 was produced by irradiating metallic sodium with slow neutrons in the pile at Harwell; thanks are due to the Isotope Division there for the repeated irradiations.
