Studies of Heavy Pear-Shaped Nuclei at ISOLDE

Peter Butler (University of Liverpool, UK)

For certain combinations of protons and neutrons it is expected that the shape of atomic nuclei can undergo octupole deformation, which would give rise to reflection asymmetry or a “pear shape”.  In this talk I will briefly review the historic evidence for reflection asymmetry in nuclei, and describe how recent experiments using REX-ISOLDE and HIE-ISOLDE, CERN have provided strong evidence that several radium and radon isotopes have either well-defined pear shapes or are octupole vibrational in nature.  I will discuss how the new measurements will help test extensions of the Standard Model through searches for atomic Electric Dipole Moments.  Finally, I will discuss the future prospects for this field.
