During the past 20 years, part of our work has been focused on the study of the atomic structure and the determination of radiative parameters in neutral and slightly ionized heavy atoms (Z ≥ 37). These elements attracted little previous interest because of the complexity of their electronic structures, the poor knowledge of their spectra, and the difficulty to perform experimental measurements. They present, however, great interest in the development of other scientific areas, such as astrophysics and plasma physics. In this paper, we give an overview of the recent progress performed by the group of Atomic Physics and Astrophysics at Mons University (Belgium) in the theoretical modelling and the experimental analysis of such heavy elements. We also discuss some applications of the atomic data obtained in our work for the interpretation of the spectra observed from astrophysical and laboratory plasmas.Key words: atomic data, oscillator strengths, radiative transition probabilities, heavy elements.Résumé : Durant les 20 dernières années, une partie de notre travail a été focalisée sur l'étude de la structure atomique et la détermination des paramètres radiatifs dans les atomes lourds neutres et faiblement ionisés (Z ≥ 37). Ces éléments avaient attiré peu d'intérêt auparavant à cause de la complexité de leurs structures électroniques, du manque de connaissance de leurs spectres et de la difficulté à réaliser des mesures expérimentales. Ils présentent cependant un grand intérêt pour le développe-ment d'autres domaines scientifiques comme l'astrophysique et la physique des plasmas. Dans cet article, nous présentons un aperçu général des progrès récents réalisés par le groupe de Physique Atomique et Astrophysique de l'Université de Mons (Belgique) dans la modélisation et l'analyse expérimentale de tels éléments lourds. Nous discutons également quelques applications des données atomiques obtenues dans notre travail pour l'interprétation des spectres observés à partir de plasmas astrophysiques et de laboratoire.Mots-clés : ions lourds, données atomiques, temps de vie radiatifs, forces d'oscillateur, probabilités de transition.
