Abstract

The nucleus 183W was studied with (n, γ), (n, γγ) and (n, nγ) reactions at the Nuclear Research Center Reactor in Riga and with the (d, p) reaction measured with the Q3D spectrograph at the Munich Tandem Accelerator. The 183W γ-transition data from the (n, γ) reaction were obtained in the energy range from 90 to 6200 keV and from the (n, nγ) reaction in the energy range from 40 to 2080 keV. The new data allowed to obtain much more accurately the energies and depopulation of excited levels, and to extend the level scheme up to about 1.7 MeV. The one-quasiparticle states below 1.6 MeV were interpreted as belonging to the Nilsson configurations 12[510], 12[501], 12[521], 32[512], 32[501], 32[521], 32+[642], 32+[651], 52+[642], 52[512], 72[503], 72[514], 92[505], 92+[624], 112+[615] and to the βγ-vibrational band. Structure calculations in terms of the quasiparticle-phonon and quasiparticle-rotation-vibration models were performed.
