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…
Reinvestigation of the excited states in the proton emitter Lu: particle-hole excitations across the subshell
F. Wang, B. H. Sun, Z. Liu +41
The excited states of the proton emitter Lu were reinvestigated in a recoil-decay tagging experiment at the Accelerator Laboratory of the University of Jyväskylä (JYFL). Th…
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…
Spectroscopic factor and proton formation probability for the d3/2 proton emitter 151mLu
F. Wang, B. H. Sun, Z. Liu +42
The quenching of the experimental spectroscopic factor for proton emission from the short-lived isomeric state in Lu was a long-standing problem. In the present…
A new technique for elucidating -decay schemes which involve daughter nuclei with very low energy excited states
M. Venhart, J. L. Wood, A. J. Boston +13
A new technique of elucidating -decay schemes of isotopes with large density of states at low excitation energies has been developed, in which a Broad Energy Germanium (BEGe) de…
Shape coexistence in neutron-deficient Hg isotopes studied via lifetime measurements in Hg and two-state mixing calculations
L. P. Gaffney, M. Hackstein, R. D. Page +24
The neutron-deficient mercury isotopes, Hg, were studied with the Recoil Distance Doppler Shift (RDDS) method using the Gammasphere array and the Köln Plunger device. T…
Characterizing the atomic mass surface beyond the proton drip line via a-decay measurements of the s1/2 ground state of 165Re and the h11/2 isomer in 161Ta
D. O'Donnell, R. D. Page, C. Scholey +33
The a-decay chains originating from the s1/2 and h11/2 states in 173Au have been investigated following fusion-evaporation reactions. Four generations of a radioactivities have bee…
First observation of excited states in 173Hg
D. O'Donnell, R. D. Page, C. Scholey +33
The neutron-deficient nucleus 173Hg has been studied following fusion-evaporation reactions. The observation of gamma rays decaying from excited states are reported for the first t…
Orbital dependent nucleonic pairing in the lightest known isotopes of tin
Iain G. Darby, Robert K. Grzywacz, Jon C. Batchelder +13
By studying the 109Xe-->105Te-->101Sn superallowed alpha-decay chain, we observe low-lying states in 101Sn, the one-neutron system outside doubly magic 100Sn. We find that the spin…
High-spin intruder band in In
E. Ideguchi, B. Cederwall, E. Ganioğlu +25
High-spin states in the neutron deficient nucleus In were studied via the Ni(Cr, 3p) reaction. In-beam rays were measured using the JUROGAM detector array…
Coulomb shifts and shape changes in the mass 70 region
B. S. Nara Singh, A. N. Steer, D. G. Jenkins +26
The technique of recoil beta tagging has been developed which allows prompt gamma decays in nuclei from excited states to be correlated with electrons from their subsequent short-l…
