Abstract
A method is proposed for determining the effective wavelength by numerical solution of an integral equation for the case of energy analysis of photoelectrons in a retarding field. With use of an FÉU-175M as a temperature sensor and temperature measurement according to dispersion of previously accelerated photoelectrons in the field of an electrostatic lens, values of the effective wavelength lie within the region of values corresponding approximately to a twofold reduction of the retarding field photoelectric current that follows from calculation based on the empirical equation.
