  The unintegrated quark and gluon distributions in the pion and nucleon are
analysed using the CCFM equations in the single-loop approximation. We utilise
the transverse-coordinate (or impact-parameter) representation which
diagonalises the equations and study in detail the dependence on the transverse
coordinate induced by the CCFM evolution. We find considerable broadening of
the transverse-momentum distributions with an increasing magnitude of the hard
scale, Q. For instance, at the Bjorken x=0.1 the root mean squared transverse
momentum of the gluons is enhanced by about 1 GeV when evolved from the the
initial low scale to Q^2=10 GeV^2, and by about 2 GeV when evolved up to
Q^2=100 GeV^2. The broadening effect is enhanced with decreasing Bjorken x, and
is stronger for the gluons than for the quarks. Analytic solution for the
average transverse momentum corresponding to the x-moments of the distributions
is obtained. The parton luminosities are also discussed.
