  • On a Special Zero of Semi-Classical Elastic S-Matrix Element 
    Piyadasa, R A D; Mallawa Arachchi, D K (Proceedings of the Annual Research Symposium 2005-Faculty of Graduate Studies, University of Kelaniya, 2005)
    A formula for semi-classical elastic s-matrix element has been derived by Brink and Takigawa (see [1]) for a potential having three turning points with a potential barrier. If Slj denotes the S-matrix element corresponding ...
  • Proof for an Algorithm to Solve the Lane-Emden Equation of index m, (m?N) 
    Dharmawardane, P.M.N.; Piyadasa, R A D; Wickramasuriya, S B P (Proceedings of the Annual Research Symposium 2005-Faculty of Graduate Studies, University of Kelaniya, 2005)
    The solution of the Lane-Emden equation is very important to understand the interior stellar structure, and is of great importance in Mathematics since the equation of index grater than one represents one class of ...
