AN ATOMIC BEAM SOURCE AND SPECTROGRAPH FOR HYPERFINE STRUCTURE. NUCLEAR MOMENTS OF SILVER

Abstract

An atomic beam source and a fast spectrograph which have been used effectively in hyperfine structure investigations are described. The camera objective of the spectrograph is an off-axis paraboloidal mirror. The procedures used to determine the nuclear moments of the two silver isotopes, I = 1/2 for each isotope, μ(Ag107) = − 0.087 n.m. and μ(Ag109) = − 0.160 n.m., are reported.
