Paschen-Back Effect of D-Lines in Sodium under a High Magnetic Field

抄録

Zeeman effect of the D-lines in sodium is investigated under a pulsed magnetic field up to about 500 kOe by using a two-layer magnet developed in the High Magnetic Field Laboratory of Osaka University. The obtained fine structure splitting under the field clearly reveals the Paschen-Back effect in the high field region in accord with the theory. The spectrum intensity is compared with the theory.
