Multiplicities of charged hadrons produced in deep inelastic muon scattering off a LiD target have been measured as a function of the DIS variables x , Q , W and the final state hadron variables p and z. The p distributions are fitted with a single exponential function at low values of p to determine the dependence of 〈p 〉 on x , Q , W and z. The z-dependence of 〈p 〉 is shown to be a potential tool to extract the average intrinsic transverse momentum squared of partons, 〈k 〉, as a function of x and Q in a leading order QCD parton model. 6 2 2 2 2 2 2 2 2 2 2 Bj T T T T Bj T ⊥ B
