The energy distribution of pions produced from 16O bombarded with 200 MeV electron was measured. The angular distribution of 16O(γ, π+)16N was deduced for the pions leading to the sum of the four lowest lying residual levels. The cross section integrated over angles is compared with the previous data deduced from the photopion yield curve. Experimental cross sections are compared with the shell model and Helm model predictions. The shell model results with configuration mixing approximately reproduce the present experimental results. The Helm model results are also similar to the experimental angular distribution pertterns.
