High-resolution photoelectron energy spectra of osmium anions are obtained using the slow-electron velocitymap imaging method.The energy levels of excited states 4F7/2,4F5/2and 4F3/2of Os- are determined to be 148.730(13),155.69(15),and 176.76(13) THz[or 4961.09(41),5193.4(49),and 5896.1(42) cm-1],respectively.The lifetime of the opposite-parity excited state 6Do9/2 is determi... 相似文献
