  We have performed electron transport and ARPES measurements on single
crystals of transition metal dipnictide TaAs2 cleaved along the ($\overline{2}$
0 1) surface which has the lowest cleavage energy. A Fourier transform of the
Shubnikov-de Haas oscillations shows four different peaks whose angular
dependence was studied with respect to the angle between the magnetic field and
the [$\overline{2}$ 0 1] direction. The results indicate the elliptical shape
of the Fermi surface cross-sections. Additionally, a mobility spectrum analysis
was carried out, which also reveals at least four types of carriers
contributing to the conductance (two kinds of electrons and two kinds of
holes). ARPES spectra were taken on freshly cleaved ($\overline{2}$ 0 1)
surface and it was found that bulk states pockets at the constant energy
surface are elliptical, which confirms the magnetotransport angle dependent
studies. First-principles calculations support the interpretation of the
experimental results. The theoretical calculations better reproduce the ARPES
data if the theoretical Fermi level is increased, which is due to a small
n-doping of the samples. This shifts the Fermi level closer to the Dirac point,
allowing to investigate the physics of the Dirac and Weyl points, making this
compound a platform for the investigation of the Dirac and Weyl points in
three-dimensional materials.
