Gh. Mei et al., DELTA-F=2-6 TRANSITIONS IN THE HYPERFINE SPECTRUM OF LAMBDA=601.8 NM LINE OF EU-151, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 39(2), 1997, pp. 115-119
The magnetic field effect of the a(8)S(1/2)-z(8)P(9/2), F = 7 transiti
on lines of Eu-151 in magnetic fields up to 400 Gauss has been studied
by using laser-atomic-beam-spectroscopy. Delta F = 2-6 transitions we
re observed. Results show that the transitions originate from the mixi
ng of the Zeeman states induced by the magnetic field. The condition f
avourable to observation of the \Delta F\ greater than or equal to 2 t
ransitions especially the transitions with high \Delta F\ values discu
ssed.
