Photoelectromagnetic (PEM) and photoconductivity (PC) measurements in n-type GaSe monocrystals are reported. The PEM and PC currents are calculated taking into account the anisotropy of the samples. From the analysis of spectral dependence the ambipolar diffusion parameters along the c axis are calculated. Estimates of lifetime and mobilities are also obtained.
