Abstract:	We study transitions between Gamma states with the emission of charged pions using 604.6 fb(-1) of data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The measured product branching fraction is B(Gamma(4S) -> Gamma(1S)pi(+)pi(-)) x B(Gamma(1S) -> mu(+)mu(-)) = (2.11 +/- 0.30(stat) +/- 0.14(sys)) x 10(-6) and the partial decay width is Gamma(Gamma(4S) -> Gamma(1S)pi(+)pi(-)) = 1.75 +/- 0.25(stat) +/- 0.24(sys)) keV.
