Seminar programme: Winter 2020-2021


The Surrey Nuclear Physics Group (NPG) holds regular seminars in experimental, 

theoretical and applied nuclear physics. Future seminars and other research activities

are displayed here. This information can also usually be found at the Departmental

web pages and, in some cases, links to the slides of the speakers are available.

Links to recent seminars, workshops and schools are also available from the Recent

Events link in the sidebar - or from here.  


Seminar venue:

Seminars usually take place at the University of Surrey. The regular venue is the Physics 

Department seminar room 30BB03. Any changes of location will be notified here. A map 

of the Surrey campus is also available here.


Forthcoming/Recent Conferences and Schools

The European Conference on Few-Body Problems in Physics (EFB24) was held

at the University of Surrey, Guildford, United Kingdom, from 2nd to 6th September 2019.

This was the 24th edition of this conference series which has, most recently, taken

place in Aarhus (2016), Krakow (2013), Salamanca (2010), and Pisa (2007).

Michael Bowry (University of the West of Scotland)

The search for nuclear pear shapes

In developing theories to explain the structure of atomic nuclei, predictions may be made

regarding their behaviour far away from the magic N and Z numbers. These expectations

drive experimentalists to seek out exotic phenomena to test nuclear models. The appearance

of reflection-asymmetric nuclear shapes is one such example where the nucleus appears

pear-shaped or, alternatively, rather like an avocado. This phenomenon occurs (for example)

in the heavy ‘actinide’ region of the nuclear chart (Z≈88, N≈136) where the presence of low-

lying excited states with angular momentum J = 3 ħ and negative-parity is evident. Such

nuclei are regarded as susceptible to octupole deformation. Some nuclei appear to oscillate

between a symmetric and an asymmetric shape (octupole vibrational) while others appear

permanently octupole deformed. In addition, reflection-asymmetry in odd-N or odd-Z

actinides has important implications in the search for the atomic electric dipole moment

(EDM), considered an important test of physics beyond the standard model. What is the

microscopic origin of reflection-asymmetry and how are these shapes inferred in experiments?

This seminar will address recent experimental and theoretical progress in this area which

has greatly accelerated in the last decade. The UK maintains a strong component of expertise

in international collaborations at radioactive ion beam (RIB) facilities such as ISOLDE and

TRIUMF with access to high-intensity actinide beams. RIB production methods and a variety

of spectroscopic techniques employed to study the octupole degree-of-freedom in actinide

nuclei will be presented.
