Quantum-Chemical Calculation of Matrix Elements in a Basis of Functions with Polynomial Tails

  • V. M. Tapilin


A numerical integration method is suggested for calculating Hamiltonian matrix elements in a basis of functions with polynomial tails with allowance for discontinuities of higher-order derivatives of the basis function within the domain of integration. The method is tested by calculating matrix elements for a copper crystal. The results for the overlap matrix elements are presented demonstrating efficiency of the method.
