Preferred Label : absorbed electrons;
Detailed label : absorbed electrons in in situ microanalysis;
IUPAC definition : The (excess) electrons present in a specimen under electron bombardment which are
led to ground and measured as specimen current. The number of absorbed electrons per
unit time (or the specimen current), equals the number of primary electrons minus
the number of back scattered, secondary and transmitted electrons per unit time. Therefore
the fraction of electrons being absorbed depends on many parameters, including the
composition and thickness of the specimen, the primary electron energy, the electron
incidence angle and local electrostatic fields when present.;
