Tidal Waves in $^{102}$Pd: A Rotating Condensate of Multiple $d$ bosons
Abstract
Low-lying collective excitations in even-even vibrational and transitional nuclei may be described semi-classically as quadrupole running waves on the surface of the nucleus ("tidal waves"), and the observed vibrational-rotational behavior can be thought of as resulting from a rotating condensate of interacting bosons. These concepts have been investigated by measuring lifetimes of the levels in the yrast band of the Pd nucleus with the Doppler Shift Attenuation Method. The extracted reduced transition probabilities for the yrast band display a monotonic increase with spin, in agreement with the interpretation based on rotation-induced condensation of aligned bosons.
