Abstract
Cesium oscillator strengths are calculated using one-electron wave functions. These functions are numerical solutions of the Schrödinger equation with a central, symmetric potential and with the spin-orbit term. The potential is chosen so that the binding energies of the lowest ten levels agree with spectroscopic values to 3%; the next 30 levels agree to better than 1%. The validity of the wave functions is demonstrated by comparison of experimental and calculated values of: (i) ratios and magnitudes of principal series oscillator strengths, (ii) fine structure splitting of the doublets, and (iii) hyperfine splitting of the ground state. Oscillator strengths are presented for over one hundred transitions in the visible and infrared. Experimental support for many of these oscillator strengths is given by line intensity measurements.
