NO. 1863 BIBLIOGRAPHY Ol* CANAL RAYS — FULCHK.R 313 



In Mercury Vapor. 



Contains first and second sub-series of triplets: 89(112, 250). 



Also XX 4358, 4047, and 2537: SHK(463, 467). 

 Doppler effect. Unquestionably observed for 12 Hg lines: 818(233); 



820f3. 



X5461. Small displacement: 85(463)- 



Observed by Paschen: 820(65). No displacement observed with 

 echelon, tension 60,000 v.: Hli ; Hl2(i3). 

 X\ 4347, 4078. Distinctly observed only with high voltages, 45,000 to 

 60,000 V. : 8HK(468) ; 813(180, 439). 

 Shift points to trebly charged atom as carrier: 8HK(468). 

 X2537. Shift points to singly charged atom as carrier: 8HK(467). 

 Lines of ist and 2nd series of triplets: 85(463); SHK(468) ; 

 820(64). 

 8ame modified shift, AX/X, for all components of a triplet and 

 for all triplets of both series: 89(112, 250) ; SHK(466) ; 

 813(181, 440). 

 Shift points to doubly charged atom as carrier: 8HK(465). 

 Displaced intensity relatively very weak, greater for higher velocities 

 and for shorter wave lengths: 813(176, 434); 820(63). 

 Effect independent of the presence of H2: 820(65). 

 Discussion of Hull's negative results: S18; HI3 ; S20; HI4. 

 In Nitrogen. See SHff2 and 3. 



Contains both the band and series line spectra of N, but band spectra 



subside as potential increases: Hr3(568) ; 8H(95). 

 Doppler effect. 



X3995. Shift distinctly observed: 85(463); 8H(94) ; Hr3(569) 

 (photo). 

 Intensity minimum well defined: 810(256). 



Width varies but slightly with cathode fall: Hr3(569). 

 Maximum shift points to singly charged N atom as carrier: 



Hr3(569). 

 XX 5006/03, 4643/3 1/22/14/07/01, 4530, etc., all show shift similar in 



appearance and amount to X 3995 : Hr3(569). 

 Band spectra show no Doppler effect: 85(463) ; Hr3(568). 

 In Oxygen. 

 Contains : 



(i) elementary line or spark spectrum of O: 01(696, 44); Win; 

 Ps3(26i); Ps4(999); 823(8x4). 



(2) series of triplets: Ps3(26i). Become weaker with higher dis- 



charge potentials: Ps4(999). 



(3) traces of bands: Win. 



Doppler effect shown by elementary line spectrum: Ps3(263) ; Ps4(998). 

 All lines in question show same displacement and appearance : 

 Ps3(263); 823(814). 

 Doppler effect for triplets even with high velocities doubtful: 8g3(i29) ; 

 Ps3(263); Ps4(998); 821(804); 823(819). 

 Intensity very weak, shift not measurable: 823(821).
