Nuclear Resonances by Extrapolation of Bound States
Nuclear resonances are decribed by the method of analytic continuation of the coupling constant (ACCC), which is an extrapolation of the trajectory of the S-matrix pole as a function of a potential strength from the boundstate to the unbound-state region. The performance of the ACCC method has been found to be excellent and independent of the nature of the decay channel and of the ratio of the imaginary to the real part of the complex energy. Some problematic states of α+nucleon- and α+α+nucleon-types nuclei have been located.
