Jul 24, 2015 at 12:28 comment added Carl Witthoft @dmckee is correct. High-energy photons can eject electrons w/ a decent speed, so it's just a matter of exceeding the binding energy.
Jul 23, 2015 at 21:33 comment added dmckee --- ex-moderator kitten When the energy of the photon very much exceeds the binding energies of the system the photon interacts with the components as if they were free. so @Carl's argument is rather misguided even though it is based on very reasonable principles: he just applying it outside it's range of validity.

Jan 3, 2014 at 13:29 comment added Carl Witthoft Hey, some of us are USAians, you (slashdot meme) insensitive clod! There are no nets in HandEgg :-)
Jan 3, 2014 at 12:53 comment added Carl Witthoft I'd basically agree: the photons which do interact, e.g. visible, X-ray, do so because their energies are a match for various excitation states of electrons or nucleii. A superhigh energy photon w/ a wavelength below the whoozis limit won't interact except for a rare kinetic collision maybe :-)
