The energy spectrum of the quasi-two-dimensional electron gas in the in-plane magnetic field is studied by means of the perturbation theory and quasiclassical approach, taking into account Rashba and Dresselhaus spin-orbit interactions. The existence of the intersection of energy sublevels in electron spectrum is demonstrated. The reciprocal mass tensor of electrons is analyzed. The heat capacity of the degenerate electron gas is examined, and its relations with the key features of the spectrum are shown.
