The Hall effect is studied in the temperature interval 2--150 K in monocrystalline molybdenum with resistance ratio rho/sub 273.2//rho/sub 4.2/ =32000. For T<80 /sup 0/K the Hall coefficient is anisotropic and has a nonmonotonic temperature dependence. An extremum in R/sub H/(T) is observed at hydrogen temperatures and is sensitive to the magnitude of the magnetic field. The observed behavior of R/sub H/(T) is explained by the Fermi surface geometry of molybdenum and by the influence of the electron-phonon scattering anisotropy. The interpretation of the experimental data is supported by a comparison of the temperature dependences of the Hall coefficient for molybdenum and tungsten.
