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). 24th European Conference on Few-Body Problems in Physics (EFB24) The conference proceedings can be found at this link
Forthcoming seminars and events
Tuesday 17th March 2020 at 14.00 in Room 30BB03 - Cancelled 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.
