Absolute f-values are determined for strong lines of Ni, Co, Au, andAg by the atomic beam absorption method of Bell, Davis, King, and Routly.The equivalent widths of the absorption lines are measured photoelectricallyand the density of absorbing atoms in the beam is determined from thebeam geometry, kinetic theory, and a microbalance measurement of theatomic beam flux. A comparison is made to existing absolute f-values and a fit is made to relative f-values in the literature.
Evidence is presented that the .1-.4 ev states of cobalt are underpopulatedin the atomic beam.
A description of the automatic microbalance, the photoelectricscanning system, and an ionization gauge used to monitor the atomic beamis given.
A review of the experimental analysis is given for the purpose ofilluminating sources of error and of defining the experimental quantities.
