Abstract
Two equivalent formulations of the microscopic cluster model, the resonating-group model and the generator-coordinate method, are reviewed. Within these frameworks, the position and widths of resonances are usually determined by calculating the phase shift function. The purpose of this lecture is to show some alternative methods for calculation of resonance parameters. Two approaches are based on imposing explicitly the Gamow asymptotics for the wave function. In a third method the resonance solution of the resonating-group equation is searched for by applying the complex scaling technique. Numerical results concerning low lying resonances in 8 Be are given.
