ionization
n 1: the condition of being dissociated into ions (as by heat or
radiation or chemical reaction or electrical discharge);
"the ionization of a gas" [synonym: {ionization}, {ionisation}]
2: the process of ionizing; the formation of ions by separating
atoms or molecules or radicals or by adding or subtracting
electrons from atoms by strong electric fields in a gas [synonym:
{ionization}, {ionisation}]

Ionization \I`on*i*za"tion\, n. (Elec. Chem.)
the process of converting neutral atoms or molecules into
ions. The process may occur by dissolving an ionic substance
in a dissociating solvent, such as water, or by adding or
subtracting an electron to or from an atom or molecule. The
latter process occurs, for example, in an electron beam in a
mass spectrometer and by interaction of substances with
{ionizing radiation}.
