Information on Service 'Tübingen Oscillator Strengths Service Form Interface'

[Use this service from your browser]

Further access options are discussed below

This service provides oscillator strengths and transition probabilities. Mainly based on experimental energy levels, these were calculated with the pseudo-relativistic Hartree-Fock method including core-polarization corrections.

For a list of all services and tables belonging to this service's resource, see Information on resource 'TOSS – Tübingen Oscillator Strengths Service'

Overview

You can access this service using:

This resource is not (directly) published. This can mean that it was deemed too unimportant, for internal use only, or is just a helper for a published service. Equally likely, however, it is under development, abandoned in development or otherwise unfinished. Exercise some caution.

Other services provided on the underlying data include:

Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD
c_wavelength Lambda_c Conventional wavelength of the transition. This is the air wavelength between 2000 and 20000 Angstrom, the vacuum wavelength otherwise. Angstrom em.wl;phys.atmol.transition
ion_stage Stage Ionisation stage N/A phys.atmol.ionStage
log_gf log(gf) Calculated HRF log(gf) (g – statistical weight of the lower level; f – oscillator strength) N/A phys.atmol.wOscStrength
species_name Atomic Number or Element A human-readable designation of the atom or molecule doing the transition. N/A phys.atmol.element

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
