We mourn the loss of our colleague and friend Maris Beitins who died on 1 June 1995 at the age of 54. P. Prokofjevs and other researchers of the Riga-Salaspils group wish to thank the Volkswagen Stiftung, Hannover, for the financial support. The authors also appreciate the help of Prof. V.G. Soloviev, Dr. T. Krasta and Dr. A.V. Sushkov, who read carefully this manuscript and made many fruitful physical remarks. A.V. Afanasjev is also grateful for financial support from the Crafoord Foundation (Lund, Sweden) and the Royal Swedish Academy of Sciences.

N2 - The nucleus 183W was studied with (n, γ), (n, γγ) and (n, n′ γ) 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, n′ γ) 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 1/2- [510], 1/2- [501], 1/2- [521], 3/2- [512], 3/2- [501], 3/2- [521], 3/2+ [642], 3/2+ [651], 5/2+ [642], 5/2- [512], 7/2- [503], 7/2- [514], 9/2- [505], 9/2+ [624], 11/2+ [615] and to the βγ-vibrational band. Structure calculations in terms of the quasiparticle-phonon and quasiparticle-rotation-vibration models were performed.
