Abstract

We propose a new technique to calculate the position and width of weak resonant states in weakly bound systems, using isospectral potentials. A new potential is constructed which is strictly isospectral with the original one but has desirable properties which make the calculation of the resonance simpler and more accurate. The usefulness of the method is demonstrated by calculating the first 1⁺ resonance in ⁶Li, using a three-body cluster model for the latter.
