Abstract
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.Keywords
