From the tables I and V we find that we get a fairly satisfactory 

 solution of (14) for a number of values (j., and 73. 



The values of ({q^) -\- ^/4 (/3 for the possible combinations {q^ q^) are 

 given in table VIII. 



Table VIII. 



With the exception of the two last combinations the total number 

 of electrons in the Z-systems [q^ -\- q^) is equal to 7. 



From a more numerical point of view the above Combinations would 

 give a fairly good agreement, and we may say that our hypothesis 

 of recombination between primaries and preservation of momentum is 

 not against the assunption of two L systems; but in thid case — as far 

 as I can see at present — such an assumption only leads to complications; 

 for it does not lead to any satisfactory explanation of the /-series. 



Putting into the equations (5 c) 



« — 3. n^ A, »3 = 2, Hi ^ 3, p^ — 3-1- V2. Pi = 2 + q-2 + Ça 

 we shall find that for all the combinations [q,), 73) given in Table VIII the 

 frequency would assume too heigh values, and would be very nearly 

 equal to that of L^^. 



When we are going to proceed further we assume that the /.-ring 

 consists of one system composed of 7 electrons. 



d. The M„-\\ ne. 



At present the J/ radiation is onlyknown for a few elements. As 

 shown in Paper I. the frequencies for the JY-lines can be expressed by 

 the emperical formula: 





2,37 K -^ 40 



••('5) 



According to this formula the J/^-line is produced by recombination 

 from a circle with quantnumber 4 to one with quant-number 3. 

 We shall treat the following two possibilities : 

 i) There is only one system with quant-number 3. 

 2) There are two ring systems.
