    • Analysis of ( 11Li+ 9Be)-reaction in the framework of the time-dependent Schrodinger equation 

      Azhibekov, A.K.; Kuterbekov, K.A.; Samarin, V.V. (2018)
      Neutron transfer and nucleus breakup cross sections in ( 11Li + 9Be) -reaction are calculated at energy range up to 32 MeV/nucleon. The evolution of probability density of external weakly bound neutrons of 11Li and the probabilities of neutron transfer and nucleus breakup are determined based on a numerical solution of the time-dependent Schrodinger equation. Our calculation ...

    • Investigation of the stability of nanostructures to degradation 

      Petrov, A.V.; Kenzhina, I.E.; Kozlovskiy, A.L.; Kadyrzhanov, K.K. (2018)
      The paper presents the dependence of the degradation degree in various aggressive media and time in a medium. The greatest deterioration in crystallographic characteristics of nanostructures in corrosive media is observed on the day 10th , which is due to partial destruction of the crystal structure as a result of oxidation processes. Also, an increase in the oxygen concentration ...
