In the experimental studies of different crystallophosphores the phosphorescence decay (Ph) is well approximated by a hyperbolic curve with an exponent less than unity ($α < 1$). Here an unconventional attempt to analyse the Ph process proceeding from the experimental Ph curves to model phosphorus is undertaken. It is suggested that at long X-ray excitation which exceeds the duration of the greatest possible registration of Ph should be described by a hyperbolic curve with $α < 1$, which gives a functional dependence of lightsum attenuation. The registration of Ph at a short-term Х-excitation on a hyperbole with $α < 1$ testifies to the fact that the Ph process is caused by the delocalization carriers at least from two types of traps.
