Seminar programme: Autumn - Winter 2018 - 2019

 

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 Conferences and Schools

The next European Conference on Few-Body Problems in Physics (EFB24) will be held

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

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

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

First measurements with the ISOLDE Solenoidal Spectrometer - probing single-

particle structure approaching the N=20 "island of inversion" via a measurement

of the 28Mg(d,p)29Mg reaction

The neutron-rich nuclei between Z=8-20 are in an interesting region of the nuclear

chart to study the evolution of single-particle structure, with several identified

phenomena to understand. To start, the N=20 shell closure has been shown to

disappear with a new gap at N=16 emerging in 24O. Whilst in the neutron-rich Si,

Al, Mg, Na and Ne isotopes a region known as the ``island of inversion" appears.

This region is characterized by deformed structures prevalent in the ground and

low-lying excitations, developing as intruder configurations from particle-hole

excitations that appear at lower excitations as shell gaps weaken.

 

In order to probe the evolution of single-particle structure approaching these

regions the 28Mg(d,p)29Mg reaction has been performed using a 9.5 MeV/u

radioactive ion beam of 28Mg from HIE-ISOLDE. This is the first physics

measurement using the ISOLDE Solenoidal Spectrometer (ISS), used to analyse

the outgoing protons from the reaction. Bound and unbound states have been

identified in the residual N=17 nucleus accounting for the majority of single-particle

strength for the negative-parity f7/2 and p-orbital, the states that arise from cross-

shell excitations. In this talk I will describe the use of the solenoid technique for

measuring direct reactions in inverse kinematics and introduce the ISOLDE Solenoidal

Spectrometer project, giving an update on its current status and future developments.

I will also present the preliminary results from the first physics measurements

mentioned above.
