Band energy parameters for all bands considered in the original paper for the odd-mass Be isotopes (left) and even-mass Be isotopes (right). Parameters considered are as follows: the rotational energy constant (top), the Coriolis decoupling parameter (middle), and the band excitation energy (bottom), which is defined as the band energy for the given band relative to that of the natural parity ground-state (or yrast) band. Bands are distinguished as natural parity ground-state (circles, solid), natural parity excited (circles, shaded), and unnatural parity ground-state (diamonds) bands. Values are shown for successive values ( for natural parity or for unnatural parity) to provide an indication of convergence (the larger symbols indicate higher values). The parameter values extracted from experimental bands are indicated by horizontal lines. The assignments for the bands are indicated at the bottom.
