Recombination coefficients for O II lines - SSB2
Listed in IVOA Registry (Virtual Observatory)
We present the results of a calculation of recombination coefficientscients for O^2 + ^+e^-^ using an intermediate coupling treatment that fully accounts for the dependence of the distribution of population among the ground levels of O^2+^ on electron density and temperature.
Description
The calculation is extended down to low electron temperatures where dielectronic recombination arising from Rydberg states converging on the O^2+^ ground levels is an important process.
The data, which consist of emission coefficientscients for 8889 recombination lines and recombination coefficientscients for the ground and metastable states of O^+^ are in Cases A, B and C, and are organised as a function of the electron temperature and number density, as well as wavelength. An interactive fortran 77 data server is also provided as an accessory for mining the line emission coefficients and obtaining Lagrange interpolated values for any choice of the two variables between the explicitly provided values for any set of wavelengths.
