Simple technique of constructing the Green’s function that is associated with the Hamiltonian, is presented. The result was applied in a case where Ho is the Hamiltonian of a free particle in given R dimensions. The theoretical concepts of field such as regularization and renomalization was introduced in order to handle the case at infinity which characterized the formal Green’s function for R  2. A comparison was also made with alternative derivation using time –independent Schrodinger equation for a particle in potential, .
