Abstract
In this paper, we investigated Stark mixing transition rate of muonic deuterium, pionic deuterium, kaonic deuterium and anti protonic deuterium exotic atoms in various density of deuterium and in various initial states. To this end, the effects of Stark mixing were studied by Borie-Leon and SCM models. In order to obtain exact results the experimental data on shift and width of and of exotic atoms were used. The obtained results show considerable transition rate of muonic deuterium in various densities and in various initial state than other exotic atoms.

Abstract
Gabbroic bodies with NW-SE trend outcropped in the southwest of Sahneh in the north of Gamassiab River, W. Iran are part of Zagros ophiolite . This complex is separated from the other geological units by deep faults and cut by pyroxenitic dikes. The field evidences, petrographic, geochemical and mineral paragenesis of these rocks are completely different from the fresh and un-altered gabbroic rocks. Furthermore the high ratios of 143Nd/144Nd (0.512945-0.513021) and low ratios of 87Sr/86Sr (0.70334-0.70656) indicate the sub-oceanic depleted mantle source for the origin of these rocks. Low variation of 143Nd/144Nd ratios, increasing of 87Sr/86Sr ratios, decreasing of SiO2 and increasing of CaO and Al2O3 mainly concludes the high reaction of gabbroic rocks with seawater. The pargenetic assemblages of altered gabbros are grossular/hydrogrossular, anderadite, epidote, idocrase (vesuvianite) and diopside. The mineral paragenesis reveals that the rodingitization was occurred by reaction of gabbroic bodies with high alkali water at a shallow depth
