The two CDW energy gaps of NbSe3were measured by means of the point contact tunneling technique. The peak to peak values of energy gaps at T=4.2K areƃtypically 2खH蝱180 mV and 2खL蝱73 mV from the NbSe3-Au junction, where खHand खLcorrespond to the higher CDW transition temperature TH=145K and lower one TL=59K, respectively. From these values, we obtained that 2खH/kTH=14.4 and 2खL/kTL=14.3, which are much larger than the DCS value.
