the spectral density operator (SDO), the projection operator that projects out of any Lz wavepacket the eigenstate( s) of H having energy E. If applied to an Lz wavepacket which overlaps the interaction, it yields either scattering-type (improper) eigenstates or proper bound eigenstates. For negativ
A procedure is presented for accelerating the convergence of the polynomial-expanded spectral density method for calculating eigenvalues and eigenvectors of a Hamiltonian. After a relatively small number of terms in the expansion, one calculates the scalar spectral function, whose plot gives informa
