Abstract


The explicit construction of the approximate wave functions for excited states is performed in the framework of a perturbative-variational method with the help of a new minimization procedure for a integral discrepancy. The numerical verification of a new approach is performed by calculating the expectation values of powers of the quartic oscillator Hamiltonian. The detail graphical verification is fulfilled by means of a local discrepancy.
