Abstract
The filter-diagonalization method is used to find the broad and even o verlapping resonances of a 1D Hamiltonian used before as a test model for new resonance theories and computational methods. it is found that the use of several complex-scaled cross-correlation probability ampli tudes from short-time propagation enables the calculation of broad ove rlapping resonances, which can not be resolved from the amplitude of a single complex-scaled autocorrelation calculation.
