  Multiplicities of charged hadrons produced in deep inelastic muon scattering
off a $^6$LiD target have been measured as a function of the DIS variables
$x_{Bj}$, $Q^2$, $W^2$ and the final state hadron variables $p_T$ and $z$. The
$p_T^2$ distributions are fitted with a single exponential function at low
values of $p_T^2$ to determine the dependence of $\langle p_T^2 \rangle$ on
$x_{Bj}$, $Q^2$, $W^2$ and $z$. The $z$-dependence of $\langle p_T^2 \rangle$
is shown to be a potential tool to extract the average intrinsic transverse
momentum squared of partons, $\langle k_{\perp}^2 \rangle$, as a function of
$x_{Bj}$ and $Q^2$ in a leading order QCD parton model.
