Abstract
The intermediate time dependence of the survival probability in two-di mensional diffusive dynamics is investigated on a model myoglobin-CO p otential-energy surface. For small diffusion anisotropy, we derive a s caling relation for the characteristic time and exponent of the observ ed power-law dependence, which is verified by exact two-dimensional ca lculations. At higher anisotropy values, we report a critical-like jum p in the anisotropy dependence of the power-law exponent. Possible exp erimental implications axe discussed.
