The fireball formed in a heavyion collision is characterized by the impact parameter
vector b, which is orthogonal to the beam direction and can be determined
from the multiplicity and the angular distribution of the reaction products. By
appropriate rotations, the b vectors of each collision can be oriented
into a fixed direction. Using the measured values of the momentum distributions of the
vector mesons, an integral equation can be formulated for the unknown emission densities
(E_{M}(r)) and for the unknown
absorption densities (Dm_{M}(r,p))
of the various vector mesons M (w^{0}, r^{0}, f^{0}, y^{0}, y^{0˘},
U).
