Effective field theory approach to rotational bands in odd-mass nuclei

We extend an effective field theory developed to describe rotational bands in even-even nuclei to the odd-mass case. This organizes Bohr and Mottelson's treatment of a particle coupled to a rotor as a model-independent expansion in powers of the angular velocity of the overall system. We carry out this expansion up to fourth order in the angular velocity and present results for ⁹⁹Tc, ¹⁵⁹Dy, ^Er,169₁₆₇, ^Tm,169₁₆₇, ¹⁸³W, ^U235_, and ²³⁹Pu. In each case, the accuracy and breakdown scale of the effective field theory can be understood based on the single-particle and vibrational energy scales in that nucleus.
