A system consisting of an ion and an electron interacting through the Hulthén potential confined in an impenetrable spherical box, with the ion at the centre is considered. Superpotential which is the crucial quantity in supersymmetric quantum mechanics is proposed for the 1s and 2p states. Variational wave functions are thence derived. Energies are calculated from these for different values of the radius of box (R) and these are compared to the exact values; good agreement is shown to exist between the two. The variational wave functions are further employed to calculate the absorption oscillator strength for the 1s→2p transition and the dipole polarizability for different values of R.

Taking into account effects of hyperfine structure, we calculated the synthetic solar spectrum for wavelength intervals around nine neutral manganese lines. To estimate values of hyperfine components we used the Oxford total absorption oscillator strength measurements (Booth et al. 1983). We compared observed profiles (Photometric Atlas of the Solar Spectrum from 3000 to 10000 ?(Delbouille et al. 1973)) of selected manganese lines with synthesized profiles in two cases: when hyperfine structure is not and when it is taken into account. By comparing the calculated with observed spectrum, we corrected the total oscillator strengths of all nine selected manganese lines.


The hook method has been used to obtain oscillator strengths for twenty lines in three branches of the (0, 0) band of the 2 ∑ + - 2 Π system of OH. It is found that vibration-rotation interaction decreases the effective f -value for this band by about 7% over the first ten lines of each branch. The absolute f -value obtained for the rotationless molecule is f 00 = (14·8 ± 1·3) x 10 -4 . Although this falls within the range of previous measurements, it is nearly twice as large as the value hitherto considered most probable. For the (1, 0) band, in which vibration-rotation inter­action could not be measured, the absolute oscillator strength is found to be (8·9 ± 1·7) x 10 -4 , giving for the relative oscillator strengths the ratio f 10 / f 00 = 0·60 ± 0·10.

AbstractThe principles and the realization of an experiment devoted to oscillator strength measurements in the vacuum-ultraviolet by the emission method are briefly presented. The results obtained for the strong multiplets of neutral nitrogen and carbon in the 1200-2000 Å range yield an absolute scale of oscillator strengths in good agreement with the most recent calculations.
