Excited Bands in Odd-Mass Rare-Earth Nuclei

Normal parity bands in ¹⁵⁷Gd, ¹⁶³Dy and ¹⁶⁹Tm are studied using the pseudo SU(3) shell model. Energies and B(E2) transition strengths between states belonging to low-lying, same-parity rotational bands in each nuclei are considered. The pseudo SU(3) basis includes states with pseudo spin 0 and 1, and 1/2 and 3/2 , for even and odd nucleon numbers, respectively. States with pseudo-spin 1 and 3/2 must be included for a proper description of some excited bands and M1 transition strengths.
