In the original publication of this article, which appeared in Pramana – J. Phys. 72(3), 457 (2009), figures 1 and 2 have been published incorrectly due to an error involved in the numerical routine which has a minor effect on the numerical values of the Jost functions for the Coulomb–Yamaguchi potential at low off-shell momentum q only and practically no difference is detected for large q values. This correction does not affect the discussions and conclusion of the original publication. The correct figures are shown here:

Figure 1

Off-shell Jost functions for Yamaguchi and Coulomb–Yamaguchi potentials as a function of q for laboratory energy 10 MeV.

Off-shell Jost functions for Yamaguchi and Coulomb–Yamaguchi potentials as a function of q for laboratory energy 30 MeV.
