Spectral Data and Grotrian Diagrams for Highly Ionized Manganese, Mn VII through Mn XXV

Abstract

Critically evaluated wavelengths, energy levels, ionization energies, line classifications, oscillator strengths, and atomic transition probabilities for Mn VII to Mn xxv are tabulated. A short review of the line identifications and wavelength measurements is given for each stage of ionization. Grotrian diagrams are also presented to provide graphical overviews. The literature has been surveyed to December 1991.

Fine-structure energy levels, oscillator strengths and lifetimes in Mn XIII

“…In a way, they correct the ab initio approach for the neglected core-valence correlation, which has been shown to contribute significantly in neutral magnesium (see, for instance Jönsson et al [22]). Our adjusted theoretical energies, 'Present (b),' are also listed in table 2 and are in excellent agreement with the experimental values [18] as well as with the NIST data. In general, the MCHF levels are in reasonably good agreement with our calculations as well as with the experimental results and the NIST data, except for the levels 3p 3 ( 2 p 0.5,1.5 ).…”

“…In table 2 our calculated excitation energies of the finestructure levels relative to the ground level for Mn XIII are compared with the experimental values compiled by Shirai et al [18] and the compiled values of the National Institute of Standard and Technology (NIST), which are available at the Website http://physics.nist.gov/PhysRefData. We have also included the ab initio levels of Froese Fisher et al [19], calculated using the MCHF method.…”

Relativistic many-body calculations of electric-dipole lifetimes, transition rates and oscillator strengths for 2l−13l′ states in Ne-like ions

“…Critical data compilations based on the available theoretical and experimental sources are given in [48][49][50][51][52][53][54][55] and online [56]. We refer to these compilations as recommended National Institute of Standards and Technology (NIST) data in the text below.…”

Relativistic many-body calculations of energies ofn= 3 states of Be-like ions

“…The experimental results were gathered and critically evaluated by a group at the National Institute of Standards and Technology (NIST). We have used the resulting data [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] for comparison. Recently, energies of 2l3l -2l2l transitions in Be-like xenon (Z = 54) were measured at the Grand Accelerateur National d'Ions Lourds (GANIL) at Caen using the Lawrence Livermore National Laboratory highresolution dual-crystal spectrometer [25].…”
