Scientists Probe Nature of Reported Low-spin Wobbling Bands in Atomic Nuclei

A research team led by the scientists at IMP has explored the nature of the reported low-spin wobbling bands in atomic nuclei. New investigation suggests that the nuclear wobbling interpretation is not feasible at low spins.Nuclear wobbling is becoming an intriguing subject as it describes a nucleus rotating around rotating axis in its body frame, in analogy with the precession in the macroscopic world. Since the firs...
