摘要：

We consider a combination of linear confining and Hulthen potentials in the Hamiltonian and, via the perturbation approach, report the corresponding Isgur-Wise function parameters. Next, we investigate the Isgur-Wise function for (B) over bar --> Dl (nu) over bar and (B) over bar (S) --> D(S)l (nu) over bar semileptonic decays and report the decay width, branching ratio, and vertical bar V-cb vertical bar CKM matrix element. A comparison with other models and experimental values is included.
