| Abstract: | In this paper, the model independent annual modulation effect observed by DAMA during four independent experiments of one annual cycle each (57986 kg day total statistics) is analysed in terms of a particle dark matter candidate which can only inelastically scatter by making a transition to a slightly heavier state, as previously suggested in the literature.
