摘　　要：本文报告了用快中子轰击天然Os靶,化学分离后,通过对W样品的γ单谱和时间序列谱的分析,发现了11条以前未知的^(189)W的新γ射线。The natural Osmium powder was irradiated with fast neutrons. After the chemical separation, the characteristic gamma ray spectra and the time-sequential spectra in the W fraction were measured. 11 new gamma lines of ^(189)W unknown previously were found.
