A generalization of the parton-like formula is used for the first time tofind the differential distributions in the inclusive semileptonic weak decaysof the B meson. The main features of this new approach are the treatment of theb-quark as an on-mass-shell particle and the inclusion of the effects arisingfrom the b-quark transverse motion in the B-meson. Using the b-quarklight-front (LF) distribution function related to the equal time momentum wavefunction taken from the ACM model we compute the electron energy spectra andthe total semileptonic widths of the B meson. We find an impressive agreementbetween the electron energy spectra calculated in the LF approach and the onesobtained in the ACM model, provided the b quark mass is identified with theaverage of the floating b quark mass in the ACM model. In spite of thesimplicity of the model we obtain a fair good description of the CLEO data forV_{cb}=0.042.Comment: 10 pages, LaTeX, 5 figures. A misprint in the title is correcte
