[en] An up-to-date compilation of nuclear data containing the main nuclear properties and parameters of the Moessbauer isotopes and their nuclear schemes regarding low energy transitions is presented. We have also considered useful to add a Moessbauer periodic table and a list of possible Moessbauer transitions. We consider that all these data as well as the table for unit transformations used in Moessbauer spectroscopy attached to the end of this paper will be of valuable help for the specialists working in the field of Moessbauer spectroscopy.
