在HI-13串列加速器上用束箔光谱学方法测量了高离化态溴离子的光谱。溴离子加速到130MeV,束流穿过25μg/cm2的碳膜。束流为200～500nA,2.2米掠入射GIM-975型真空紫外单色仪被用来探测箔膜后被激发离子发出的光。谱仪方向与束流垂直,在狭缝为20μm时,谱线宽度为0.02nm。在离子能
The spectrum of highly ionized bromide ions was measured by beam foil spectroscopy on a HI-13 tandem accelerator. The bromide ion is accelerated to 130 MeV and the beam passes through a 25 μg / cm2 carbon membrane. Beam 200 ~ 500nA, 2.2 meters grazing incidence GIM-975 type vacuum UV monochromator is used to detect the foil after the excited ions emitted light. The direction of the spectrometer is perpendicular to the beam. When the slit is 20 μm, the spectral width is 0.02 nm. In ion energy
