Comparison to other experimental data, TALYS calculations and KADONIS-1.0 data. Photoneutron reactions were measured with quasi-monochromatic photon beam at NewSubaru synchrotron radiation facility using 4π detector consisting of 20 3He proportional counters. Experiment on inelastic α-scattering was performed at the Oslo Cyclotron Laboratory (OCL) using CACTUS NaI(Tl) scintillator γ-ray detector array, the Silicon Ring (SiRi) detector array and beam from MC-35 Scanditronix cyclotron.
