Abstract

We present a simple model for the

γ N \to π π N

reaction which reproduces the cross sections of the

π^{+} π^{-} p, π^{+} π^{-} n, π^{+} π^{0} n

, and

π^{-} π^{0} p

channels over the range of the energies 0.41–0.85 GeV. We use the dynamical model for the resonances

Δ (1232)

, and

N^{*}

(1520) and the

ρ

meson. The total photoabsorption off a nucleon is also discussed.
