Abstract A method is presented which permits the determination of relative initialp-state populations and combineds- andd-state populations of beam-foil excited hydrogenic atoms from Lyman and Balmer decay curves. The method utilizes exact and linear cascade relationships which exist between corresponding portions of these decay curves when they are measured under common excitation conditions, and does not involve exponential curve fitting. The technique determines (but does not require a measurement of) the relative normalizations of the various decay curves by a simple linear regression, thus inferring initial populations from the renormalized relative intensities as extrapolated to the foil position. The basic relationships of the method are developed, and results are presented from a computer study of the quality of data which would be required to extract populations by this technique.
