Query: Absolute measurement of the Fano factor using a Skipper-CCD   Skipper-CCD can achieve deep sub-electron readout noise making possible the
absolute determination of the exact number of ionized electrons in a large
range, from 0 to above 1900 electrons. In this work we present a novel
technique that exploits this unique capability to allow self-calibration and
the ultimate determination of silicon properties. We performed an absolute
measurement of the variance and the mean number of the charge distribution
produced by $^{55}$Fe X-rays, getting a Fano factor absolute measurement in Si
at 123K and 5.9 keV. A value of 0.119 $\pm$ 0.002 was found and the
electron-hole pair creation energy was determined to be (3.749 $\pm$ 0.001) eV.
This technology opens the opportunity for direct measurements of the Fano
factor at low energies.
