  The rapidity distribution of gluons produced in heavy ion collisions is
studied by a numerical computation in 2+1-dimensional classical Yang-Mills
theory. By assuming that the classical source strength g^2 mu depends on
rapidity as g^4 mu^2 ~ exp(+- lambda y) and studying collisions of two nuclei
with different g^2 mu we find that the rapidity distribution of produced gluons
at central rapidities is very broad. The transverse energy is seen to decrease
even more slowly as a function of y than the multiplicity. We discuss these
results and the range in y and sqrt(s) where they are applicable in the light
of experimental results and other theoretical calculations.
