The quadrupole excitations of transuranic nuclei are described in the frame of the microscopic Bohr Hamiltonian modified by adding the coupling with the collective pairing vibrations. The energies of the states from the ground-state bands in U to No even--even isotopes as well as the B(E2) transition probabilities are reproduced within the model containing no adjustable parameters.
