Abstract：
Taking into account the pairing plus quadrupole-quadrupole interaction, the intrinsic properties of the low-lying bands (even parity) and the related E2 transition probabilities in ¹⁶⁸Er were calculated in the frame of Bohr-Mottelson-Nilsson model. The agreement between the calculated and the observed results is satisfactory. Some difficulties encountered in the IBM prediction do not appear in the present calculation.
