Metallic Ge ( 17 g weight, 3 mm thickness, 27 mm 4078400100035 distance from neutron source target) was irradiated. 4078400100036 Gamma radiation with energy 0.157+-0.01 MeV and 4078400100037 HL=(16+-1) msec was detected. The cross section for 4078400100038 production of 0.17-MeV metastable level was determined 4078400100039 to be 0.3 b.
