Laser intensity-dependent peak locations of the EN and Esum spectra. a The energy of the first and second ATI peaks of the Esum spectra of the direct and one-photon pathways of the (H+, H*) channel as a function of the laser intensity. b Laser intensity-dependent locations of the peaks of the EN spectra of the direct and one-photon pathways of the (H+, H*) channel. The statistical error bars for \(E_{{\rm N}({\rm H}^+{\hbox{,}}\ {\rm H}^{\star})}\) represent the uncertainty of Gaussian fits of the EN spectra during data analysis. The black dotted lines indicate the calculated low limit of the EN related to the direct and one-photon pathways
