Karazin popup.description2 The alpha-cluster model with dispersion for the 24Mg nucleus has been constructed. The form factor of the magnesium nucleus has been calculated and the differential cross section of the intermediate-energy proton elastic scattering by magnesium nuclei has been investigated theoretically. The magnesium nucleus density parameters determined from the theoretical analysis of experimental data on the form factor of this nucleus have been used to calculate the differential cross sections of the proton-nucleus scattering and to compare results of these calculations with corresponding experimental data. Investigations of the kinetic, thermodynamic and acoustic properties of the superfluid helium(HeII) have been carried out. The energy spectrum of ripplons in He II has been studied. Investigation of relaxation processes in the isotropic and anisotropic quasiparticle systems of He II has been carried out. Studies of the collective modes in the anisotropic quasiparticle systems of He II have been performed. The calculation results explain experimental data. Product Description popup.authors Адаменко І.
