We use a non-gauge-invariant modification of the exact Hamiltonian to obtain a new Hamiltonian-like operator for a simple exactly solvable boson model. The eigenvalues of the new operator are close to those of the original Hamiltonian. We make a one-

A bounded operator is introduced so that rigorous constrained variational calculations can be performed. With this operator the calculations are no more complex than previous, nonrigorous calculations and no dependence on unphysical parameters is int

The elastic scattering cross section for neutrons on oxygen is calculated beginning with a realistic nucleon-nucleon interaction. A soft interaction is employed so that a perturbation expansion is tractable. The results reinforce the conclusions deri

An independent particle model is obtained from the fundamental constrained variational equations for a many-body system by making certain assumptions. The resulting model contains the attractive feature of the Nilsson model but has the advantage of a

It is demonstrated in finite-range DWBA analyses of (p, t) reactions, utilizing realistic triton wave functions, that the transfer only occurs in the extreme surface of the nucleus. This explains in part the success of recent (p, t) analyses which em

The validity of the results of finite basis, constrained variational calculations with unbounded operators has remained unquestioned despite the mathematical difficulties in an infinite basis pointed out by Fonte and Schiffrer. It will be shown here

The method developed by Boguliubov for an imperfect Bose-Einstein gas is generalized in order to permit examination of a mixture of an arbitrary number of different species of bosons. The generalized method involves diagonalization of a matrix that h

The Strutinsky method for extracting the shell corrections from the Nilsson model has been interpreted in the framework of constrained Hartree-Fock theory. Cast in this form, the shell corrections, the smooth part of the energy and those terms ignore
