The creation and direct detection of n-particle atomic correlations in
ensembles of atoms is investigated. For this, we study an ensemble of
laser-driven atoms in which either a dipole-dipole or a Rydberg-Rydberg
interaction leads to the formation of correlations between the internal degrees
of freedom of the atom. We show that light scattering can be used to imprint
information about these correlations onto light, and reveal how this
information can be extracted from the statistical properties of the scattered
light. As main result we find that observation in certain detection directions
allows to directly and individually measure n-particle atomic correlations.
Complementary, we discuss a method to experimentally determine the interesting
detection positions.
