Study of the Parameters of a Thallium Atomic Beam by the Laser Resonant Atomic Photoionization Technique

摘要

The arrangement and operating principle of a setup for studying the main parameters of a beam of thallium atoms using the laser resonance atomic photoionization technique and the experimental results obtained are presented. The measured characteristics are the evaporation time, the atomic beam intensity, the evaporation rate, the saturated vapor pressure, and the heat of thallium evaporation.
