“…The unknown elements in the first column are then obtained by assuming the same ratio also for them. The elements in the second column are evaluated by the same method as above, thus using the ratio between (4, 2 ) and ( 5 , 2) to determine the other elements (6, 2), (7,2 ) and (8,2). Table IXb indicates that this procedure gives a reasonable picture of the perturbations.…”

The spectrum of neutral phosphorus has been studied photographically at Lund with a pulsed high-frequency electrodelessdischarge in the regions 11Ofh2700 A and 4000-11 500 A. The Fourier transform spectrograph at Laboratoire Aim6 Cotton, Orsay, has been used for recording the region 10 00040 000 A with a microwave tube as a light-source. In all, 1800 P I transitions have been measured and classified.A total of 282 levels, about 180 of which are new, have been established. The levels belong to the configurations 4s-9s, 3 p d p , 3d-9d, 4f-9f, and 6g in the 3 ~* 3 p ~( ~f l n I system, 4s, 5s, 4p, 3d of the ('D)nZ system and to ('S)4s. Of the configuration 3s3p4 the terms 4P and 2D are known while 2P and *S, predicted to fall above the Fist ionization limit, are still missing. The effects of the perturbations between (3flnd, sp4 and ('D)3d have been studied by parametric calculations of the composite configuration sp4 + 3d t 4d + 5d.

“…The assigned lines of P I were limited to several dozen in the first decades of the 20th century. Robinson [2] photographed the emission spectrum of phosphorus with a Geissler tube discharge in 1936. Combining this with earlier works, he identified 22 terms and assigned 36 lines for P I.…”

The absorption spectrum of neutral phosphorus was recorded in the range 7700–8256 Å using optical heterodyne magnetic rotation concentration modulation spectroscopy with a tunable Ti:sapphire laser as the light source. Phosphorus atoms were excited by discharging the mixed gases of phosphorus vapor and neon gas. The phosphorus vapor was prepared by heating white phosphorus chips placed on a cylindrical copper electrode during discharge. In total, 234 lines of P I were observed, of which 127 were assigned. The transition frequencies were obtained with an uncertainty of 0.007 cm−1. Empirical line intensities were provided covering four orders of magnitude.

“…The spectrum of atomic phosphorus was first investigated by Geuter (1907). Subsequent observations and analyses made by Kiess (1932), Robinson (1936), Martin (1959) and most recently by Svendenius (1980) and Svendenius and Vergès (1980) have led to the identification of the 3s3p 4 terms and 3s 2 3p 2 nl terms up to nl = 9s, 6p, 9d, 9f and 6g.…”

The photoabsorption spectrum of atomic phosphorus has been recorded in the 1400-600 Å region. The Beutler-Fano profiles due to autoionizing 3s 2 3p 3 4 S → 3s3p 3 ( 5 S)np 4 P (5 n 14) transitions have been observed and fitted to a Rydberg series. Calculations made with the Cowan code show that interaction with the 3p −2 3d4p (also written as 3s 2 3p3d4p) configuration is negligible, unlike the situation for 3s photoexcitation in Ar I.
