Resonance and Continuum Components of the Strength Function

Abstract

It is shown that the strength function can be expressed as a sum of the contributions from bound, resonance and continuum terms and that the role of each term can be investigated complementarily by using the complex scaling method (CSM). The mechanism of the Coulomb breakup reaction of11 Be is analyzed, and we confirm the fact that the breakup is direct but not through resonances. The present method is also applied to other systems and its usefulness is discussed.
