Ab initio calculations including relativistic effects in the Breit-Pauli R-matrix (BPRM) method are reported for fine structure energy levels and oscillator strengths upto n=10...

We report measurements of the relative intensities of 81 emission lines of Fe II between 160nm and 350nm (62168cm^-1^ to 28564cm^-1^) from 4 levels by high resolution Fourier...

A number of diatomic molecules have been found in vibrationally excited states in several cosmic objects. The molecules in vibrationally excited states provide valuable...

Following tentative detection of cyclopropene (C_3_H_4_) in Sgr B2 through its transition 3_22_-2_21_, several attempts to confirm the presence of cyclopropene in astronomical...

The tables include data concerning six He-like ions: wavelengths, transition probabilities, wavelengths at which the radiation temperatures should be determined. Line ratios (G...

Theoretical line strengths and transition probabilities for electric quadrupole (E2) transitions between levels belonging to several important configurations of Co16+ are...

Effective collision strengths for transitions between 92 fine structure states calculated in a Breit-Pauli approximation are provided in ups.dat. Results are provided for log T...

Effective collision strengths for transitions between 86 fine structure states calculated in a Breit-Pauli approximation are provided in ups.dat. Results are provided for log T...

A new set of radiative and electron collisional data for Fe XII was presented in two earlier papers. In the present work, we derive level populations and theoretical line...

The electron-impact widths for 30 Zr III lines were calculated using the modified semi-empirical (MSE) method. For two Zr II and four Zr III astrophysically important UV lines,...

This paper reports R-matrix calculations of electron impact excitation rates for Ni III. The calculation includes 70 LS terms corresponding to the configurations 3d^8^, 3d^7^4s,...

We tabulate theoretical line strengths, f-values and transition energies for the beryllium-like ion Fe XXIII. Transitions are between levels 2l_1_2l_2_S'L'J' and 2l_3_nl_4_SLJ...

Tables 2a-f and 4a-f contain an extensive set of parameters derived from our grid of C-type (tables 2a-f) and J-type (tables 4a-f) planar stationary shock models. Models of...

Numerous papers on the solar photospheric abundance of iron have recently been published leading to a longstanding debate concerning rather different results obtained from the...

Tables 1&2 correspond to the first estimate of the error factors affecting the {beta} decay rates of highly ionized heavy atoms in stellar environments. The uncertainties in...

A sample of the agreement between experiment (recent experimental log(gf) values) and our method (orthogonal operator technique) is shown in table 1. The experimental data are...

In this paper, a chemical model of interstellar clouds including ^18^O and ^13^C isotopic reactions with a non-LTE calculations of ^16^O^18^O rotational population has been used...

Spectroscopic properties of SiO have been calculated from highly correlated wave functions. The computed dipole moments for v=0-3 agree well with the experimental data of...

Table ls.dat contains all LS terms considered in this work and their energy values with complete designation. Table aij.dat contains f-, S-, and A-values of transitions, both in...
