ti_16.wgfa (radiative data)

contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.

%A values for transitions indicated within the ground configuration: Merkelis et al., 1999, Physica Scripta 59, 122
%A values for allowed n=2 transitions: Zhang, Sampson, ADNDT, 1999, 72, 153

ti_16.splups (electron collision data)

contains the spline fits to the electron collision strengths scaled according the rules formulated by Burgess and Tully (1992). Accurate replication of the temperature averaged collision strength over a wide range of temperatures can be accomplished with the data in this file.

 

%filename: ti_16.splups
%oscillator strengths (levels 1 - 15): Zhang, Sampson, 1999, ADNDT, 72, 153
%%oscillator strengths (levels 16 - 72): Bhatia,A.K., Seely,J.F., Feldman,U., 1989, ADNDT, 43, 99
%collision strengths (levels 1 - 15): Zhang, Sampson, 1999, ADNDT, 72, 153
%collision strengths (levels 16 - 72 only from the ground): Bhatia,A.K., Seely,J.F., Feldman,U., 1989, ADNDT, 43, 99
%comment: the original collision strengths for levels 16 - 72 were calculated only at one single energy.
