Abstract
For the transfer of an excitation on a periodic linear chain with excitation-phonon interaction, the authors have determined quantitative limits for the ranges of three types of memory-function behaviour (coherent, incoherent and quasi-coherent) for microscopic input parameters and temperature. The dependence of transition rates on real microscopic quantities and temperature is calculated.Keywords
