The E2 admixtures in mixed multipole lines 459.7 and 564.0 nm of Bi IThis paper was presented at the International Conference on Precision Physics of Simple Atomic Systems, held at University of Windsor, Windsor, Ontario, Canada on 21–26 July 2008.

Abstract

Studies of the M1-E2 interference effect in the Zeeman spectra of forbidden lines 459.7 and 564.0 nm of Bi I are reported. By the use of computer modelling techniques, the simulated contours were fitted to the recorded spectra to determine the electric-quadrupole admixture in forbidden lines. The E2 admixtures found are: (3.49 ± 0.35)% and (37.1 ± 1.8)% for 459.7 and 564.0 nm lines, respectively. Our results are compared with recent theories and other experiments.

Observation of the M1–E2 interference in the Zeeman spectra of isotopes121Sb and123Sb

“…This work continues our earlier studies of the M1-E2 interference effect in the Zeeman spectra of heavy atoms [1][2][3]. We considered two mixed-type (M1+E2) lines 541.5 and 609.8 nm of Sb I.…”

Fine, hyperfine and Zeeman structures of levels of 123Sb I

“…This work is a continuation of our earlier studies of the hfs and Zeeman structures of heavy atoms [13][14][15][16][17][18][19][20][21][22][23][24]. Measurments were performed to investigate fourteen strongest emission lines in the near visible and infrared region of isotope 123 Sb (see Fig.…”

“…In the experiment the metallic isotope 123 Sb was used. A standard experimental arrangement for observation of hfs and Zeeman structures described in details in a series of our previous papers [13][14][15][16][17][18][19][20][21][22] was used. An electrodeless discharge tube powered by a RF generator (55 MHz) was the source of radiation.…”
