Single g-ray spectra and gg-coincidences, following thermal neutron capture in ¹²⁴Te, were measured with semiconductor detectors at the light-water reactor LWR - 15 at Řež. Intensities of g transitions in ¹²⁵Te were normalized using the absolute intensity of 7.8% of the 6620 keV line in ³⁶Cl. The high resolution (d,p) measurements were performed with 17 MeV deuterons, using the Q3D spectrograph at two scattering angles of 15^° and 30^°. Spectra were recorded in the range up to 3.3 MeV and calibrated using the proton peaks with l =1, and the corresponding level energies were determined in the thermal neutron capture reaction. The (³He,a) experiment was carried out with a 32 MeV He beam at the angle of 10^°. The spectrum was recorded in one run by means of a large detector in a range up to approximately 4.7 MeV. The absolute intensities were determined by measuring the total beam current.
