Extended Data Fig. 4: Measured delay- and angle-resolved photoelectron spectrum.
From: Attosecond-resolved non-dipole photoionization dynamics
a Measured delay- and angle-resolved photoelectron spectrum for peak1 (Ek = [10.0, 11.4] eV). b Normalized photoelectron spectrum, \({{{\mathscr{I}}}}(\theta ,\tau ;{E}_{k})={{{\mathscr{M}}}}(\theta ,\tau ;{E}_{k})-\overline{{{{\mathscr{M}}}}}(\theta ;{E}_{k})\), shown in Eq.(6) of the main text. c The asymmetry of the normalized photoelectron spectrum, \({{{\mathscr{I}}}}(\theta ,\tau ;{E}_{k})-{{{\mathscr{I}}}}(\pi -\theta ,\tau ;{E}_{k})\).
