Abstract
The many-channel quantum defect method has been used for the calculation of the photoionization cross section of ground-state nitrogen atoms in the dipole length approximation. The calculations couple three channels corresponding to the 2s2 2p2 and 2s2p3 configurations of the residual ion. The results obtained are in agreement with experiment for the energy region between the ionization limit and 1 rydberg unit beyond.
