Optical double resonance and zero field level crossing spectroscopy applied to the 5p ³ 6s ⁵ S ₂ level in the Te-I spectrum

Abstract

As a first application of optical double resonance and zero field level crossing spectroscopy to the elements of the sixth group in the periodic table of the atoms, the 5p ³6s ⁵ S ₂ level in the Te-I spectrum was investigated using natural tellurium in a high temperature quartz cell. For the electronic Landé-factor and the natural radiative lifetime the following values were obtained:

$$g_J \left( {5p^3 6s^5 S_2 } \right) = - 1.9657\left( {12} \right),\tau \left( {5p^3 6s^5 S_2 } \right) = 71.8\left( {2.2} \right)ns.$$
