An experiment on the scattering of 23 MeV deuterons by Be nucleus was carried out. Differential scattering cross sections are obtained for the following states: g.s., 1.68 MeV, 2.43 MeV, 2.78 MeV, 3.05 MeV, 3.82 MeV, 4.70 MeV, 5.59 MeV, 6.38 MeV, 6.76 MeV and 7.94 MeV. The obtained data were analyzed using the distorted wave Born approximation (DWBA) and modified diffraction model (MDM). It was confirmed that the positive parity band 
= 
based on the 1.68 MeV, state is formed by the 3.05 MeV, 
; 4.70 MeV, 
and 6.76 MeV, 
states. It was proposed that the 3rd band ( = 
) based on the 2.78 MeV, state may be formed by the 5.59 MeV, 
and 7.94 MeV, 
states. The radii of these band states ( = and = ) are increased compared to the ground state. Besides, it is found that the 3.82 MeV state has 
= and does not belong to any of the rotational bands considered above. Possibly, it is formed as a one-particle state near the excited 
Be core with the spin 
= 2.
