Rate coefficients are calculated for the formation of O(II) lines by r
ecombination. Photoionization data from the Opacity Project are used t
o calculate recombination coefficients for principal quantum numbers,
n less-than-or-equal-to 10, including radiative and dielectronic recom
bination. Cascading from higher states is included, allowing for the e
ffects of finite electron density in a hydrogenic approximation.
