Argentina Centro de Investigaciones Opticas. 1900 La Plata. Rep. ArgentinaABSTRACTThe spectrum of xenón emitted by a non-conventional light source has been studied. About 123 lines are classified in the range 2100 - 6750 A.RESUMENHa sido estudiado el espectro del xenón em itido por una fuente luminosa no convencional. Son clasificadas alrededor de 123 I fneas en el rango de 2100 - 6750 A.1. INTRODUCTIONReyna Almandos et al (1) recently reported results ¡n the spectrum o f  singly ¡onized xenón. A bou t 40 lines were classified in the 2000 • 2800 A range belonging to 6s-4f and 5d-4f transitions.An extended compilation of lines o f the xenón spectra by Gallardo and Reyna Almandos (2) shows that there are many unclassified lines distributed throughout the whole wavelength range investigated.The present work has made use o f this compilation and a d d i t ion a l  material for classifying 123 lines corresponding to 5d-6f, 6s-7p, 5d-7p, 6s-6p, 4f-5g, 8s-6p, 7s-4f, 6s-4f, 5d-4f, 5d-5f, 5d-6p, 6d-4f, 6d-5g, 6p-7s, 6p-8s, 6p-5g, 6p-6g, 6p-6d, 6p-5d, 7p-5g, 7p-8s, 7p-6d, 4f-6g and 4f-7g transitions.2. EXPERIMENTAL METHODSAll spectra were produced in puré xenón confined in a tube originally designed for pulsed láser operation. The light source is similar to that described by Reyna Almandos et al (1).Spectrograms were recorded using thorium (3) as a reference spectrum, and the probable wavelength error seldom exceeds 0.05 A, 0.03 A and 0.01 A for lines measured in the first, second and third diffraction orders respectively.Systematic shifts, resulting from the use of a non-conventional light source, were frequently found.A  c o m p a ra t io n  between lines measured by Humphreys (4) and those determined w ith  our source revealed shifts that are different for different transitions, the  máximum differences aobs- a H u m ph re ys  6eing about 4- 0.6 cm—1 corresponding to 6p-6d and 6p-7s transitions. However, greater shifts can be observed in other transitions, but not systematically.Full experimental details are given in (1), which also assign 50 new lines to  Xe II spectra.3. RESULTSNot only the wavelengths listed in (2) but also a number of lines corresponding to unpublished material (5,6) has been used for classifying the Xe II lines. P a rto f  this matrial (6) contains new lines and the revised ionic assignation o f a group of lines that is reported as Xe II or Xe l l - l l l  in (2).A l l  Xe II lines were classified in accordance with data obtained in A E L  (7) and modifications proposed by Hansen and Person (8) are given in Table I. The third and fourth columns o f the table give the wavenumber of the lines and show the degree o f agreement between observed and calculated valúes taking into account the shifts in our lines.163TABLE IClassified Xe II Lines in the Región 2100—6800 A Comments o f lines shapes: A =  asymetric; B =  blended; H =  wide Symbols in column five; a =  unpublished material (5,6); b =  revised assignation164TABLE I (Continued)165TABLE I (Continued)166TABLE I (Continued)O 3773.83 26490. 78 . 16 ( 3P i )5d [2 ] s^ - ( 3P2)7 p [1] ^0 3810.67 26234.68 5.81 ( *D2)5 d [2 ] 5^ - ( 3P2) 7p[2] 3^1A 3883.35 25743.69 .26 ( 3D2) 5d[ 2] 3P 1 ) 4 f[0 3962.15 25231.67 .71 ( 3P i ) 6p [ 1]! - ( 3D2)7s [2 ]  3^  a1 4 0 03 .0 9  249 73 .6 6  2 .6 5  ( 3P 1 ) 6 p [ 2 ] 5^ - (  3P 1 ) 6 d [ 2 ]0 4026.82 24826.50 .02 ( 3P0)5d [2 ] 3^ - ( 1D2) 6p [2]0 4112.42 24309.71 .78 ( 3Pa)6p [2 ] 3^ - (  3P2) 8s[2]0 4131.24 24199.01 98.00 ( 3P i )6 p [2 ]s £ - (3P2) 83[2]s/20 4215.30 23716.46 .98 ( 3P2) 7s[2] 5^ - (  3D2 )4 f  [2 ]  5/z3B 4237.96 23589.65 8. 75 ( 3P2 )5 d [3] 5¿ - (*D 2 ) 6p [3]1A 4295.17 23275.40 4.93 ( 3P i ) 6p[ 1] 3^ - (  3P2) 8s[2] 3^2 4310.58 23192.24 .14 ( 3P2) 5d[ 315^ - (  'Dz) 6p[ 1 ] 3^  b0 4357.28 22943.61 4.59 ( 3P2) 7 s [2 ] 5^ - (  1D2) 4 f [  1] 3^  a0 4392.09 22761.76 .23 ( 3P j ) 6s [ 1 ] i^ - (  3D2) 6pC 1 ] 3^  a1 4404.54 22697.49 .41 ( ^ j . ) 6p [3 ] 3P2) 5 g [2 ]S/z0 4427.53 22579.59 .41 ( 1D2 )6 p [3 ]5/2- (  3Pz) 5g[4] 7^  a0 4488.97 22270.56 .35 ( 3P2) 4 f [ 4 ] , ^ - ( 3P i)  5g [3 ]7/i a0A 4508.97 22171.82 . 71 ( 3P2) 4f [ 3 ] s^-( 3P 1 ) 5g[4] 7^2B 4550.91 21967.50 .26 ( 3P0 ) 6p[ 1] i^ - (  3P 1 ) 7s[ 1 ] 3^1 4591.80 21771.882 14 591 .9 4  ¡ 21771.22 2 ‘ ° 2 ( 3P , ) 6.C 1 ] ’ P i ) 6p[ 1 ]5 í 4629.83 21593.04 2>24 ( 3P2) 7p[ 3] 5/ - ( 3P 1 ) 5g[ 3]5 (4629.99 21592.29 2 .09 ( 3PZ)7pC3 ]5, - ( 3P 1 ) 5gC3 ]s,4 4630.26 21591.00 *1H 4673.94 21389.23 8.65 ( 3D2) 6p[ 3] 7/2- ( 3P2) 5g[4]<>^3 4675.42 21382.49 .65 ( 'ü^ópC 3] 7^ - (  3P2) 5g[4] 7^1H 4681.65 21354.04 j ' 77 K ’ M  4 f[ 5] ( *P i ) 5BC 5 3,^3.82 ( 3P2 ) 4 f [5 ]9 ^ - ( 3Pi)5gC5]n^167TABLE I (Continued)O 4685.86 21334.83 .59 ( 3P2) 4 f [ 5 ] ^ - ( 3Pi )  5gC3] ^  aIB (4692.05 21306.714B | 4692.15 21306.22 ' 93 ( 3P2)6d[4 ]<^-(  1D2) 4 f [4 ] ,^4 4709.08 21229.62 8.41 ( 3P2 ) ¿*fC¿*3T^-(3Pi)  5gC5D9^0 4713.76 21208.55 } ' 23  ( ( P 2 )4 f [ 4 ] 7^ - (  P i )5g[  3]?^ a/ .08 / ( sP2)4f [4]7A - ( 3P i ) 3 g [3 ] 5^3 4727.82 21145.51 4.30 ( 3PZ) 4f  [ 2] 5^ - (  3P2) 5g[4 ] 7^1A 4798.35 20834.66 .82 ( 3P2) 6d[ 4 ] 7, - ( ^ 2 ) 4 f [ 4 ] 7,f i fi2B 4831.08 20693.55 4.36 ( 3P2) 6d[ 3] 7, - ( % )  4 f [ 5 ] 9,f l  f lIB 4841.85 20647.52 8.40 ( % )  5d[ 3 ]5/- ( 3P2) 7p[ 3] i Lf i  f l3 4847.82 20622.10 3.22 ( 3P2 ) 6 d [4 ] 7/- ( 1D z )4 f [3 ]S/h  í i0 4938.90 20241.79 40.29 ( 3P 2) 4 f [ 5 ] 9, - ( 3P2) 7 g [ 5 ] 1 1 ,f i h0B 5040.06 19835.52 .54 ( 3P2)4 fC5 ] 1 1^ ( 3P0) 5g [4],^0 5019.91 19915.09 6.28 ( 3P2 ) 6d[ 2 ]S/- ( 3D2 ) 4 f [ 1 ] 3/ ah  h1 5570.91 17945.40 .81 ( 3P2 ) 4 f [  4],.  - ( 3Pz )6g [ 6 ] , 1 af l f lO 5730.56 17445.45 .92 ( 3P2) 7p[ 3] 3P 1 ) 8s[ 1 ] 3O 5849.28 17091.35 9 0 ,9 0  ( ( ^ 2) 4 f [5 ]  1 y-( P2 ) 6g [5] 1 a.84 ) ( 3P 2 ) « [ 5 ] n /- ( 3P2)6g[5] ,/í;4 5889.82 16973.75 .33 ( 3P2) 4 f [ 5 ] 9/- ( 3P2)6 g [4 ] ,  af l f l4 5891.70 16968.31 9.27 ( 3P2 ) 4 f [ 5 ] , . - ( 3P2 ) 6 g [ 5 ] 1 j. af i h2 6457.96 15480.51 79.29 ( 3P2) 7 p [2 ] 5, - ( 3D2 ) 6d [2 ] 3/f i  hO 6502.47 15374.52 . 31 ( 3P 1 ) 6 p [0 ] j . - ( 3P2) 6p [ 1 ] j.f l  hO 6510.06 15356.59 .62 ( 3P2) 8s [2] 3^ - ( 1 D2 ) 6p [ 2 ] 5^O 6512.28 15351.38 50.98 ( 3P 1 ) 6p[ 1] 3. - ( )  5d[ 2] 3/f i  hO 6 5 36.33 1 5 2 9 4.8 8 3.45 ( 3P2) 6p [ l ] - ( 3P )6d[2 ] , .h  2  f l3 6619. 33 15103.11 2.78 ( 3D2)6p[2]5, - ( 3P2)8 s [2 ]5,f l  f lOA 6649.81 15033.87 5.27 ( 3P2 ) 7 s [ 2 ] 3, - ( ‘ S0) 6p [ 1 ] 1 ,f l  f lO 6697.65 14926.49 5.29 ( 3P,0) 6p[ 1] 3, - ( 3P2) 6d[ 1 ] j.h /2O 6744.27 14823.30 .23 ( 1 D2 ) 6p [ 1 ] , , - ( 3P2 ) 8s [ 2 ] 3, af l f lACKNOWLEDGEMENTThe authors wish to thank Dr. W.
