UNMAPPED\_GLYPHS on p\. 2 \(Omega in the harmonic frequency\)\. WHY NOTHING IS TAKEN\. The measured and computed quantities are harmonic spectra and conversion efficiencies, not ionisation rates or yields; the ionisation rates themselves appear only as Figs\. 4\(a\) \(p\. 3\) and 5\(a\) \(p\. 4\) \(He, YI against ADK rate against time, at 400 nm, 8\.5 x 10^14 W/cm^2, gamma ~ 1, and at 800 nm, 7\.4 x 10^14 W/cm^2, gamma = 0\.52; text p\. 5\)\. The paper prints no rate formula of its own and does not say which YI prefactor it used\. No table\. EXPERIMENT MODELLED \(Falcão\-Filho et al\., Appl\. Phys\.
