Enhancing the performance of solenoidal spectrometers for inverse reactions
P. A. Butler
Helical-orbit solenoidal spectrometers, in which the target and detector are placed inside a uniform magnetic field, have been utilised for more than a decade to study nuclear reac…
The observation of vibrating pear shapes in radon nuclei: update
P. A. Butler, L. P. Gaffney, P. Spagnoletti +41
There is a large body of evidence that atomic nuclei can undergo octupole distortion and assume the shape of a pear. This phenomenon is important for measurements of electric-dipol…
Evolution of Octupole Deformation in Radium Nuclei from Coulomb Excitation of Radioactive Ra and Ra Beams
P. A. Butler, L. P. Gaffney, P. Spagnoletti +40
There is sparse direct experimental evidence that atomic nuclei can exhibit stable pear shapes arising from strong octupole correlations. In order to investigate the nature of octu…
First Exploration of Neutron Shell Structure Below Lead and Beyond
T. L. Tang, B. P. Kay, C. R. Hoffman +26
The nuclei below lead but with more than 126 neutrons are crucial to an understanding of the astrophysical -process in producing nuclei heavier than . Despite their im…
The SPEDE spectrometer
P. Papadakis, D. M. Cox, G. G. O'Neill +18
The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct me…
Direct Evidence of Octupole Deformation in Neutron-Rich Ba
B. Bucher, S. Zhu, C. Y. Wu +31
The neutron-rich nucleus Ba (=11.5 s) is expected to exhibit some of the strongest octupole correlations among nuclei with mass numbers less than 200. Until no…
