Charge carrier transport in a typical molecularly doped polymer has been st
udied by the time-of-flight and radiation induced conductivity methods. In
the time range bracketing the conventional transit time a strong disagreeme
nt between two sets of data has been found. Unlike time-of-flight signal th
at rather closely reproduces all salient features reported in literature, t
he radiation induced conductivity transient lacks the plateau. In fact, it
exhibits a strict power law decay t(-0-5) changing at long times to t(-1) o
r t(-1.5) patterns due to bimolecular recombination or true transit time ef
fects, respectively. At short times, both transients are described by the s
ame t(-0.5) dependence. These facts suggest the dispersive rather than the
Gaussian charge transport.
