New models of Jupiter are based on observational data provided by the Galileo spaceprobe, which considerably improved previously existing estimates of the helium abundance in the atmosphere of Jupiter. These data yield for Jupiter's atmosphere 20% of the solar oxygen abundance and do not agree with the results of the analysis of the collision of comet Shoemaker-Levy 9 with Jupiter (10 times the solar value). Therefore, both the models of Jupiter with water-depleted and water-enriched atmosphere are considered. By analogy with Jupiter, trial models of Saturn with a water-depleted external envelope are also developed. The molecular-metallic phase transition pressure of hydrogen Pm was taken to be 1.5, 2 and 3 Mbar. Since Saturn's internal molecular envelope is noticeably enriched in the IR-component (its weight concentration, 0.25-0.30, being by a factor of 3-4 higher than in Jupiter), the phase transition pressure in Saturn can be lower than in Jupiter. In the constructed models, the IR-core masses are 3-3.5 M⊕ for Jupiter and 3-5.5 M⊕ for Saturn. Jupiter's and Saturn's IR-cores can be considered embryos onto which the accretion of the gas occurred during the formation of the planets. The mass of the hydrogen-helium component dispersed in the zone of planetary formation constitutes ~2-5 planetary masses for Jupiter and ~11-14 planetary masses for Saturn.
