How to measure the Ionization Energy of metals?
« on: September 08, 2013, 03:25:43 PM »
How do scientists the Ionization Energy of metals? I mean do they first evaporate the metal and then apply a high voltage? doesn't it take a huge amount of energy? or there's another way?

thanks.

According to the definition of ionization energy , the element must be in gaseous state. Though , in photoelectron spectroscopy the metal is used in its solid form. I can't understand how this amount of energy shows the ionization energy , whereas the element is not a gas during electron emission.
