The transverse magnetophonon resonance in high purity epitaxial n-InP was investigated at temperatures between 123 and 270 K. High pulsed magnetic fields up to 40 T were applied to observe the fundamental resonance field. The temperature dependence of the magnetophonon effective mass m0 at the band-edge was precisely determined through the analysis of the resonant field positions including the peak for N=l. The determined value of m0 is 0.019mo at 270K and 0.084mo at 143 K. The magnetic field dependence of the damping factor was found to be yaB2/3 in magnetic fields higher than 10 T. The temperature dependence of the damping factor was also obtained.
