There is an on-going need for accurate oscillator strengths to be used in astrophysical applications, particularly in plasma diagnostics and in the modelling of stellar atmospheres and the interstellar medium.

There are several databases in regular use which contain some of the required data, although often insufficiently complete, and sometimes not sufficiently by: 3. We present the FERRUM Project, an international collaboration aiming at a production and evaluation of oscillator strengths (transition probabilities) of selected spectral lines of singly ionized iron group elements, that are of astrophysical relevance.

The results obtained include measurements and calculations of permitted and forbidden lines of Fe II. Journal Article: Oscillator strengths and transition probabilities for allowed and forbidden transitions in Fe XIX. Abstract. I have been asked by the Chairman of the Conference to say something about future laboratory work on Fe II.

In a way it is impossible to make a specification of the future experimental program at the laboratories, where measurements of atomic parameters of Fe II are in : Sveneric Johansson.

In spectroscopy, oscillator strength is a dimensionless quantity that expresses the probability of absorption or emission of electromagnetic radiation in transitions between energy levels of an atom or molecule.

The oscillator strength can be thought of as the ratio between the quantum mechanical transition rate and the classical absorption/emission rate of a single electron oscillator with.
