Theoretical results are presented for the photodissociation cross section of H 2 + from the 1s sigma g ground electronic state to the vibrational continuum of the 2p sigma u state. Values of the cross section have been calculated for rotational states 0<or=J<or=8. A total cross section has been evaluated for temperatures 2500<T(K)<26000, in the wavelength region 500<or= lambda (AA)<or=25000, assuming a Boltzmann distribution. The variation of the cross section with temperature is discussed. It is concluded that for T>or=10000K, the total cross section would be improved by including more rotational states. An empirical extrapolation procedure is proposed using the available results to obtain cross sections accurate at high temperatures.
