Abstract
The cross sections for charged-pion photoproduction from $^{16}\mathrm{O}$(${0}^{+}$, g.s.) leading to the four low-lying bound states ${J}^{P}={2}^{\ensuremath{-}}, {0}^{\ensuremath{-}}, {3}^{\ensuremath{-}}, {1}^{\ensuremath{-}}$; $T=1$ in $^{16}\mathrm{N}$ are calculated in the Woods-Saxon basis. Two-particle-two-hole correlations in the ground-state wave function of $^{16}\mathrm{O}$ are taken into account. Calculations in the Woods-Saxon basis yield more realistic results for the cross sections near the first pion-nucleon resonance region, where high momentum transfers occur, than those obtained in the conventional harmonic-oscillator basis.
