Fine structure and isotope shift of the 3s4d 3 D-3s3p 3 P, 3s5d 3 D-3s3p 3 P and 3p 2 3 P-3s3p 3 P Transitions of MgI

Summary. --We report the measurements of the 3D(3s4d)-3P(3s3p), 3D(3s5d)--ap(3s3p), and 3P(3p2)-3p(3s3p) transition frequency of MgI, the free-structure separation and isotope shift between 2aMg and 26Mg. The measurements have been performed in a metastable atomic beam; a good agreement is found for data already existing in the literature. The accuracy of the measurements reported in this paper is mainly limited by the Doppler broadening of the/2 transitions used as a reference and by the precision in the knowledge of the related wavelengths.PACS 32.30.Jc -Visible and ultraviolet spectra. High-resolution spectroscopic studies of the first-excited states of Mg have been performed mainly in recent years; the fine-structure splittings of the metastable triplet 8p(0) are reported in [l,2], the isotope shifts and hyperfine splittings in [3][4][5]. Moreover, the isotope shift and hyperfine splittings of the following transitions have been measured: 3s4s 8S-3s3p 3p [6,7], the 3s3d 3D-3s3p 3p [8,9], the 3s4d 3D-3s3p 8p [9] and 3s 21S o-3s3p 1P 1 [10].The transitions between the terms Sp(3p2), ~D(3s4d), and SD(3s5d), and the term 3p(0) (3s3p) of MgI fall in the (277 + 310) nm wavelength range, covered by frequency duplication of the rhodamine dyes.A high-resolution investigation of these terms is interesting in order to complete the literature data. In fact, except for the 3D(3s4d) fine-structure splittings, already cited above, the major work on the matter remains the one of Risberg [ll] who measured about 160 lines of MgI and whose data make the body of a critically compiled collection of energy levels of MgI [12]. That work was performed with classical hollow-cathode discharge lamps and isotope shifts were not resolved. We have performed the measurements in a metastable atomic beam which assures a sub-Doppler resolution to the experiment. The source of radiation is a commercial 955

“…The two models were developed to investigate whether the additional configuration interaction terms influenced the resulting collision strengths in any way. Energy levels produced by the two models are presented in Table 6, along with those of Zhang et al (1994) and experimental energies of Martin & Zalubas (1980). From Table 6 it can be seen that all but 5 of the M1 energies are within 1% of the experimental values.…”

Context. Mg  emission lines are observed in a range of astronomical objects such as the Sun, other cool stars and in the coronal line region of Seyfert galaxies. Under coronal conditions Mg  emits strongly in the extreme ultraviolet (EUV) and soft X-ray spectral regions which makes it an ideal ion for plasma diagnostics. Aims. Two theoretical atomic models, consisting of 125 fine structure levels, are developed for the Mg  ion. The 125 levels arise from the 2s 2 2p, 2s2p 2 , 2p 3 , 2s 2 3s, 2s 2 3p, 2s 2 3d, 2s2p3s, 2s2p3p, 2s2p3d, 2p 2 3s, 2p 2 3p and 2p 2 3d configurations. Electron impact excitation collision strengths and radiative transition probabilities are calculated for both Mg  models, compared with existing data, and the best model selected to generate a set of theoretical emission line intensities. The EUV lines, covering 312-790 Å, are compared with existing solar spectra (SERTS-89 and SUMER), while the soft X-ray transitions (69-97 Å) are examined for potential density diagnostic line ratios and also compared with the limited available solar and stellar observational data. Methods. The R-matrix codes Breit-Pauli RMATRXI and RMATRXII are utilised, along with the PSTGF code, to calculate the collision strengths for two Mg  models. Collision strengths are averaged over a Maxwellian distribution to produce the corresponding effective collision strengths for use in astrophysical applications. Transition probabilities are also calculated using the CIV3 atomic structure code. The best data are then incorporated into the modelling code CLOUDY and line intensities generated for a range of electron temperatures and densities appropriate to solar and stellar coronal plasmas.Results. The present effective collision strengths are compared with two previous calculations. Good levels of agreement are found with the most recent, but there are large differences with the other for forbidden transitions. The resulting line intensities compare favourably with the observed values from the SERTS-89 and SUMER spectra. Theoretical soft X-ray emission lines are presented and several density diagnostic line ratios examined, which are in reasonable agreement with the limited observational data available.

Chinese hamster ovary (CHO) cells have frequently been used in biotechnology for many years as a mammalian host cell platform for cloning and expressing genes of interest. A detailed physical chromosomal map of the CHO DG44 cell line was constructed by fluorescence in situ hybridization (FISH) imaging using randomly selected 303 BAC clones as hybridization probes (BAC-FISH). The two longest chromosomes were completely paired chromosomes; other chromosomes were partly deleted or rearranged. The end sequences of 624 BAC clones, including 287 mapped BAC clones, were analyzed and 1,119 informative BAC end sequences were obtained. Among 303 mapped BAC clones, 185 clones were used for BAC-FISH analysis of CHO K1 chromosomes and 94 clones for primary Chinese hamster lung cells. Based on this constructed physical map and end sequences, the chromosome rearrangements between CHO DG44, CHO K1, and primary Chinese hamster cells were investigated. Among 20 CHO chromosomes, eight were conserved without large rearrangement in CHO DG44, CHO K1, and primary Chinese hamster cells. This result suggested that these chromosomes were stable and essential in CHO cells and supposedly conserved in other CHO cell lines.
