摘要: The results of the first precise measurement wavelength dependence photodetachment cross section negative atomic hydrogen ion in range from 0.4 to 1.3 mu are reported. was accomplished by improving signal-to-noise ratio experiment through improvement preamplifier detection sensitivity and elimination background signals developing a direct, reliable method for relative determination light intensity photon beam.
