Abstract
The X-ray spectrum associated withK − stopping in liquid hydrogen was measured with high resolution Si(Li) detectors. The totalK X-ray yield is not larger than 8×10−4 per stoppedK − assuming no line broadening. A weak line pattern was found, which was tentatively ascribed to theK − HK-series X-rays. The shift and width of the 1s level, deduced from this pattern, are ε1s =+270±80 eV andΓ=560±260 eV, respectively.
