In previous works, where SAR’s were studied within the time-independent close-coupling method, we found that in addition to the energy width obtained by analyzing plots of diffraction intensities versus the energy of the incident beam, another internal energy width (with a very different numerical value) can be defined. Here we show that it is this internal width that can be directly related to the lifetime of the resonance. Also, we have performed a simulation of the half collision or ‘‘selective-desorption’’ process. This approach is shown to yield accurate values for lifetimes of SAR’s. © 1994 The American Physical SocietyThis work has been partially supported by the CICYT Grant No. PB87-0272 and Comunidad de Madrid Grant No. 064/92.
