Resolving anomalous collectivity in the to transition of Fe
J. A. Woodside, B. J. Coombes, A. E. Stuchbery +7
The low-excitation states of atomic nuclei in the region around the shell closure are generally well described by the shell model. Most experimental observables in the…
Coulomb excitation of Te: Emerging collectivity and persisting seniority structure in the level
M. Reece, B. J. Coombes, A. J. Mitchell +9
The low-lying energy spectra of even-even tellurium isotopes near midshell have long been interpreted as `textbook' examples of vibrational collective motion. However, in many case…
Evolution of the nuclear spin-orbit splitting explored via the Si(,)Si reaction using SOLARIS
J. Chen, B. P. Kay, C. R. Hoffman +30
The spin-orbit splitting between neutron 1 orbitals at Si has been deduced using the single-neutron-adding (,) reaction in inverse kinematics with a beam of …
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…
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…
Electric monopole transition from the superdeformed band in Ca
E. Ideguchi, T. Kibédi, J. T. H. Dowie +14
The electric monopole () transition strength for the transition connecting the third 0 level, a "superdeformed" band head, to the "spherical" 0 ground state in do…
Quenching factor measurements of sodium nuclear recoils in NaI:Tl determined by spectrum fitting
L. J. Bignell, I. Mahmood, F. Nuti +21
We have performed measurements of sodium nuclear recoils in NaI:Tl crystals, following scattering by neutrons produced in a Li(p,n)Be reaction. Understanding the light…
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}…
