Intrinsic quadrupole moments for the self-consistent deformed Hartree-Fock-Bogoliubov (HFB) shapes for the even Ti, Cr, and Fe isotopes are calculated and compared with results obtained from the self-consistent Hartree-Fock (HF) approximation. It is pointed out that in the HFB approximation for even $Z<N=28\mathrm{}$ nuclei one gets spherical shapes, and hence to calculate the $B\left(E_2\right)$ rates it is not proper to use the deformed HF wave functions. We calculate the $B\left(E_2\right)$ rates with the excited-state wave functions constructed over the spherical BCS solutions in the random-phase approximation.
