Level-Crossing-Untersuchung des 6p 2P3/2-Terms im Au I-Spektrum durch Resonanz­streuung von Licht im elektrischen und magnetischen Feld zur Bestimmung der Hyperfeinstrukturtermordnung / Stark Effect Investigation of the 6p 2P3/2-State in Au I -Spectrum in Order to Determine the Signs of the Hyperfine Structure Constants

D. Einfeld, J. Ney and J. Wilken

Level crossing technique, applying parallel electric and magnetic fields, has been used to determine the signs of the hyperfine structure constants A and B as well as the magnitude of the Stark-constant β . From the Stark-shift of the signal at 45 Oe in the wing of the Hanle-effect and of the level-crossing near 140 Oe to higher magnetic field strengths the ratios A/β > 0 and B/ß > 0 could be determined. An estimation of β by calculating the electric dipole matrix elements with Coulomb approximation yields a positive sign. Both signals and their shift with electric field then can be explained with the following results:

A = + 14.0 (5) Mc/sec; 5=+327.6 (1.6) Mc/sec and β= +5.7(3) (kc/sec) (kV/cm)-2.
