Collision induced transitions between Zeeman substates of laser excited sodium atoms in very high magnetic fields

Abstract

This is a report on a new method of measuring cross sections for the collision induced population transfer between single Na — 3p 2 P fine structure Zeeman states. The experiments are done for the five inert gases at the magnetic field strengths of 6, 17, 24, and 51 kOe. From the optically excited2 P 3/2,±3/2 and2 P 1/2,±1/2 states, respectively, the transfer to the other Zeeman states is studied. The method allows the determination of cross sections for which the influence of the magnetic field is cancelled and which render possible the calculation of cross sections for the transfer and the relaxation of all2 P density tensor components of the degreek=1, 2, and 3. The comparison with previous theoretical and experimental results gives satisfactory agreement. As an application the six Grawert parameters are deduced for the inert gases.
