ition (222-* 002). (The relativity modifications would, as mentioned above, giverise 

 lo the appearance of this component with a small intensity inversely proportional 

 to the square of the electric force, but it is easily seen that in the present case this 

 effect must be expected to be much less than in the case of the analogous compo- 

 nent in Hß.) A discrepancy between the values of R' - and the observed intensities 

 seems to exist in the case of the weak parallel components. Thus the component at 

 J = 12 appears stronger, while the component at J = 20 appears perhaps weaker 

 than it would be expected from the corresponding values of R'^. Further the per- 

 pendicular component at J = 6 appears stronger than we should expect from the 

 table. These discrepancies are more or less analogous to those observed in case of 

 H^; thus the parallel component at J = 12 and the perpendicular component at 

 J = 6 may be considered as analogous to the components J = 5 and J = in 

 Hy, and correspond also to transitions for which the electron in the final state [002] 

 describes a circular orbit. As regards the problems in question it may further 

 be oliserved that, especially in Iho case of Hy and the value /j = 2 in the final
