  Energy levels of the four lowest bands in 160,162,164Dy and 168Er, B(E2)
transition strengths between the levels, and the B(M1) strength distribution of
the ground state, all calculated within the framework of pseudo-SU(3) model,
are presented. Realistic single-particle energies and quadrupole-quadrupole and
pairing interaction strengths fixed from systematics were used in the
calculations. The strengths of four rotor-like terms, all small relative to the
other terms in the interaction, were adjusted to give an overall best fit to
the energy spectra. The procedure yielded consistent parameter sets for the
four nuclei.
