Oscillator Strengths for the Continua of CA II.

Values of df/d~ have been found at several points in the 4s-p, 4p-s, 4p-d, 3d-p, and 3d-f continua of Ca ii. The wave functions for the continua were found by numerical integration of the Schrodinger equa- tion omitting exchange terms but with Hartree's values of the self-consistent field, with exchange, of the Ca~ ion introduced. Two sets of wave functions were used for the bound states. The first set was that of Hartree and included exchange. The second set was found in the same manner as were the wave functions for the continua. The physical reality of the values found for df/d~ is discussed at some length
