      More Details Abstract Fulltext PDF

      The usual method of peratization technique is to expand scattering lengthA(a) in Born series in powers of the coupling constantg. In this paper a new approach to the peratization technique has been discussed starting with the standard equation for the scattering length. As an application of the theory developed, the cases of inverse fourth power and a logarithmic singular potentials have been discussed.

    • Exact solutions of Dirac equation

      More Details Abstract Fulltext PDF

      In this paper Dirac equation for two electromagnetic potentials viz vector potential and scalar potential have been solved. These solutions of the Dirac equation are written in terms of known solutions of the Schrödinger equation. The presentation is within the two-component relativistic description. Mainly the bound state solutions have been obtained.

      More Details Abstract Fulltext PDF

      Peratisation scheme normally used to obtain scattering lengtha(α) is through Born series. In this paper an iteration approach to this technique has been presented. This approach has also been applied to different potentials successfully.
