“…Using this formalism they obtained good agreement between the theoretical and experimental levels with a standard root mean square deviation of less than 20 keV for 224,226 Ra and 224,226 Th [40]. Similar methods have been applied to explain the high-spin behaviour of 220 Ra [41] (see section 3) and 144,146 Ba [42].…”

“…For these N=90 nuclei the low-lying collective negative-parity bands cross bands built on particle-hole excitations that are well described by the Cranked shell model [75]. For the N=86 nuclei 144 Ba, 146 Ce, 148 Nd and 150 Sm, HFB calculations [76] predict a phase transition from octupole vibrational to octupole deformation as I approaches 10ÿ.…”

The experimental and theoretical evidence for octupole collectivity in nuclei is reviewed. Recent theoretical advances, covering a wide spectrum from meanfield theory to algebraic and cluster approaches, are discussed. The status of experimental data on the behaviour of energy levels and electric dipole and electric octupole transition moments is reviewed. Finally, an outlook is given on future prospects for this field.

“…An approach advocated here is to employ (d, d ) scattering (see, e.g. [9]) to populate low-lying states in odd-A nuclei via single-step excitation. We have carried out simulations that indicate that ∼ 20 keV energy resolution for the final states can be reached by using the HELIOS-type spectrometer, provided that the radioactive heavy beams are cooled in a storage ring such as the TSR.…”

It is planned to install the heavy-ion, low-energy ring TSR, currently at the Max-Planck-Institute for Nuclear Physics in Heidelberg, at the HIE-ISOLDE facility in CERN, Geneva. Such a facility will provide a capability for experiments with stored, cooled secondary beams that is rich and * Presented at the XXXIV Mazurian Lakes Conference on Physics, Piaski, Poland, September 6-13, 2015.(627) 628 P.A. Butler et al.varied, spanning from studies of nuclear ground-state properties and reaction studies of astrophysical relevance, to investigations with highly-charged ions and pure isomeric beams. In addition to experiments performed using beams recirculating within the ring, the cooled beams can be extracted and exploited by external spectrometers for high-precision measurements. The capabilities of the ring facility as well as some physics cases will be presented, together with a brief report on the status of the project.

“…An approach advocated here is to employ (d,d') scattering (see, e.g. ref 17) to populate low-lying states in odd-A nuclei via single-step excitation. We have carried out simulations that indicate that ~ 20 keV energy resolution for the final states can be reached by using a helical orbit spectrometer (HELIOS) such as that developed at the Argonne National Laboratory [18], provided that the radioactive heavy beams are cooled in a storage ring.…”

For certain combinations of protons and neutrons there is a theoretical expectation that the shape of nuclei can assume octupole deformation, which would give rise to reflection asymmetry or a "pear-shape" in the intrinsic frame, either dynamically (octupole vibrations) or statically (permanent octupole deformation). In this talk I will briefly review the historic evidence for reflection asymmetry in nuclei and describe how recent experiments carried out at REX-ISOLDE have constrained nuclear theory and how they contribute to tests of extensions of the Standard Model. I will also discuss future prospects for measuring nuclear shapes from Coulomb Excitation: experiments are being planned that will exploit beams from HIE-ISOLDE that are cooled in the TSR storage ring and injected into a solenoidal spectrometer similar to the HELIOS device developed at the Argonne National Laboratory.
