Shape polarization in the tin isotopes near from precision -factor measurements on short-lived isomers
T. J. Gray, A. E. Stuchbery, J. Dobaczewski +16
The factors of isomers in semimagic Sn and Sn (isomeric lifetimes ns and ns, respectively) were measured by an extension of th…
A Time Projection Chamber to Search for Feebly Interacting Bosons via Proton Induced Nuclear Reactions
Martin Sevior, Michael Baker, Lindsey Bignell +7
We propose a new Time Projection Chamber particle detector (TPC) to search for the existence of feebly-interacting bosons and to investigate the existence of the X17 boson, propose…
Direct measurement of hexacontatetrapole, γ decay from Fe
T. Palazzo, A. J. Mitchell, G. J. Lane +11
The only proposed observation of a discrete, hexacontatetrapole () transition in nature occurs from the T = 2.54(2)-minute decay of Fe. However, there are confl…
Hyperfine fields at Ga, Ge implanted into iron and gadolinium hosts at 6 K, and applications to g-factor measurements
T. J. Gray, A. E. Stuchbery, B. J. Coombes +7
Isomers in Ga, Ge, and Ge were recoil-implanted into ferromagnetic hosts of iron and gadolinium at ~K, and the hyperfine magnetic fields were determ…
Pulse Shape Discrimination of low-energy nuclear and electron recoils for improved particle identification in NaI:Tl
N. J. Spinks, L. J. Bignell, G. J. Lane +20
The scintillation mechanism in NaI:Tl crystals produces different pulse shapes that are dependent on the incoming particle type. The time distribution of scintillation light from n…
Gamma-ray and conversion-electron spectroscopy of the high-spin isomer in 145Sm
Matthew Gerathy, Gregory Lane, Andrew Stuchbery +11
Background: High-spin isomers at {\approx}9-MeV excitation energies have been reported in several N = 83 isotones near Z = 64. Spin and parity assignments of J{^π} = 49/2+ remain t…
Improved precision on the experimental E0 decay branching ratio of the Hoyle state
T. K. Eriksen, T. Kibédi, M. W. Reed +35
Stellar carbon synthesis occurs exclusively via the process, in which three particles fuse to form C in the excited Hoyle state, followed by electromagnetic decay t…
Emerging nuclear collectivity in Te
B. J. Coombes, A. E. Stuchbery, J. M. Allmond +11
The emergence of nuclear collectivity near doubly-magic Sn was explored along the stable, even-even Te isotopes. Preliminary measurements of the $B(E2;4^{+}_{1}…
Solenogam: A new detector array for -ray and conversion-electron spectroscopy of long-lived states in fusion-evaporation products
Matthew Gerathy, Gregory Lane, George Dracoulis +15
A new detector array, Solenogam, has been developed at the Australian National University Heavy Ion Accelerator Facility. Coupled initially to the SOLITAIRE 6.5 T, gas-filled, sole…
Table of electronic factors for E0 electron and electron-positron pair conversion transitions
J. T. H. Dowie, T. Kibédi, T. K. Eriksen +1
A new tabulation of electronic factors is reported for electron conversion for elements of Z from 5 to 126 and electronic factors for electron-positron pair conversion for elements…
First-excited state factors in the stable, even Ge and Se isotopes
B. P. McCormick, A. E. Stuchbery, B. A. Brown +15
Transient-field -factor measurements in inverse kinematics were performed for the first-excited states of the stable, even isotopes of Ge and Se. The factors of Ge an…
High-resolution conversion electron spectroscopy of the 125I electron-capture decay
B. P. E. Tee, A. E. Stuchbery, M. Vos +5
The conversion electrons from the decay of the 35.5-keV excited state of 125Te following the electron capture decay of 125I have been investigated at high resolution using an elect…
Spectroscopy and excited-state ~factors in weakly collective Cd: confronting collective and microscopic models
B. J. Coombes, A. E. Stuchbery, A. Blazhev +9
The even cadmium isotopes near the neutron midshell have long been considered good examples of vibrational nuclei. However, the vibrational nature of these nuclei has been question…
Perturbed angular distributions with LaBr detectors: the factor of the first state in Cd revisited
T. J. Gray, A. E. Stuchbery, M. W. Reed +10
The Time Differential Perturbed Angular Distribution technique with LaBr detectors has been applied to the isomeric state ( keV, ~ns) in…
