THE ABSORPTION SPECTRUM OF BaI IN THE REGION OF AUTOIONIZATION FROM 2382 TO 1700 A.

Abstract

The atomic absorption cross section of barium has been measured in the autoionization region at an instrumental bandwidth of 0.075A between 2380 and 2100A and 0.75A between 2100 and 1700A. The cross sections of the absorption features whose half-widths approach the bandwidth of the monochromator have been corrected to eliminate the bandwidth dependence. The observed structure is grouped into series and presented with measured wavelengths and a parameter F. The latter is numerically equal to the oscillator strength of the transition, except when significant perturbations from neighboring lines or the underlying continuum occur. Evidence of the presence of elements in the series 6pns singlet P(1) and triplet P(1) n > 6 is presented. (Author)
