在4.000 ~ 13.000埃范围内测量了氢原子负离子的光电散射截面与光谱的关系，分辨率约为300埃。用25个带通滤波器进行测量，每个测量值相对于用5280 A的对照滤波器获得的值进行。对于每个滤波器获得的相对值，可能存在约2%的误差。结果与现有的计算截面有很大的差异。（auth）
The spectral dependence of the photodetachnnent cross section for the negative ion of atomic hydrogen was measured in the range from 4.000 to 13.000 A with approximately 300-A resolution. Measurements were made with twenty-five band pass filters, each measurment taken relative to the value obtained with a control filter at 5280 A. A probable error of about 2% is attached to the relative value obtained for each filter. The results are in significant disagreement with available calculated cross sections. (auth)
