  We use the author's previous work on atomic decompositions of Besov spaces
with spectrum on symmetric cones, to derive new atomic decompositions for
Bergman spaces on tube type domains. It is related to work by Ricci and
Taibleson who derived decompositions for classical Besov spaces from atomic
decompositions of Bergman spaces on the upper half plane. Moreover, for this
class of domains our method is an alternative to classical results by Coifman
and Rochberg, and it works for a larger range of Bergman spaces.
