A direct and an indirect method for accurate measurement of absolute intensities of low-energy γ-rays from neutron capture and radioactive decay by means of a crystal spectrometer is described. The 478-keV peak of Li 7  (target B 10 ) is used in the direct method while the 412-keV peak of Hg 198  (target Au) is used in the indirect method. In addition the intensity calibration of the crystal spectrometer used in FRM (Munich Research Reactor), determination of the neutron capture rate and corrections for γ and neutron self-absorption are discussed in some detail. Absolute γ-intensities per neutron capture or decay respectively were determined for a number of strong low energy γ transitions in Rh 104 , Cd 114 , Sm 150 , Sm 153 , Eu 152 , Eu 153 , Eu 154 , Gd 156 , Gd 158 , Dy 162 , Dy 163 , Dy 164 , Dy 165 , Ho 165 , Ho 166  and Er 166 . An accuracy of 2% was obtained in the most favorable cases.
