Multiconfiguration Hartree-Fock calculations for photodetachment cross sections in Ca{sup {minus}} are reported, both to the {ital ks} {sup 2}{ital S} and {ital kd} {sup 2}{ital D} final state. Correlation is important to the binding of the 4{ital s}{sup 2}4{ital p} {sup 2}{ital P} state and also to the cross section. In the final state, correlation is particularly important for the {ital kd} partial cross section. The value of the electron affinity in Ca{sup {minus}} is critical to agreement in the length and velocity form of the cross section. Better agreement is obtained when a theoretical value is used. Agreement with an experimental photodetachment cross section is good.
