We identified 88 states resonantly excited at energies from 3.7 to 8.2 MeV. The analysis of the measured g-ray spectra includes the quasicontinuum of levels at high energy. Monte Carlo simulation of g-ray cascades were performed to obtain the intensities of inelastic transitions and branching ratios of the ground state transitions. The extracted photo-absorption cross section show enhanced dipole strength at the excitation energies around 5.5 and 7 MeV, which may related to a pygmy dipole resonance. The present (g,g) data combined with (g,n) data from the literature were used for confining input parameters of the statistical calculation code CCONE to derive the neutron capture cross section of the unstable 205Pb nucleus.}, pages = {1--12}, title = {Dipole strength distribution in 206Pb for the evaluation of the neutron capture cross section of 205Pb}, volume = {98}, year = {2018} }
