Abstract A singlesγ-ray spectrum and a spectrum of summed amplitudes of coinciding pulses (SACP) were measured in the186W(n, γ)187W reaction experiment on the thermal neutron beam. It was for the first time that the data on187Wγ-transitions were obtained in the excitation energy region from 1500–2500 keV. The neutron binding energy was determined to beB n=5467.25 (4) keV (statistical error only). In result the level scheme of187W was developed in the excitation energy interval 1〈E f 〈 3.4 MeV, which contained 105 levels with about 70 of them being identified for the first time. The experimental values for summed intensities of two-step cascades were established to exceed those predicted by the modern statistical theory (by 36±6%). This is explained by a considerable contribution of few-quasiparticle components to wave functions of compound and intermediate states.
