Abstract

The direct spectroscopic method was used in which the spectrum was excited by electron impact. The accelerating voltage on the electrons was varied 8.8 (ionization potential of Cd) up to 200 volts. Measurements on the films were made with a microphotometer. The effects of change of plate current and vapor pressure were investigated.
