Abstract: | A new method of determining the nuclear level density is presented. This method is based on the statistical analysis of the partial width fluctuations appearing in an excitation function of the radiative proton capture. The method was applied in the case of the 88Sr(p, γ0)89Y and89Y(p, γ0)90Zr reactions. The density of levels with spin 1? in 90Zr and the densities of levels with spins and in 89Y at excitation energies from 10.9 to 11.6 MeV and from 9.3 to 10.8 MeV respectively, were determined with an uncertainty of about 35%. |
