Kerman's Problem in the Continuum

In 1956 Kerman published a seminal paper on rotational perturbations in nuclei [1]. Since then, Coriolis and rotational alignment effects have been extensively studied and are rather well understood [2,3]. With the development of exotic beam facilities and advanced instrumentation it is becoming possible to access regions of deformation in the nuclear chart, near the neutron drip-line. Here, the effects of weak binding are expected to play an important role, affecting the dynamics of the nuclear motion. In this work we study Kerman's problem when the single-particle levels involved are resonant states. We will present results showing the behavior of the kinematic and dynamic moments of inertia as a function of the state widths. Connection to possible experiments will be discussed. \\ \\ 1. A. K.
