Double-magic nature of 132Sn and 208Pb through lifetime and cross-section measurements

Single-neutron states in Sn133 and Pb209, which are analogous to single-electron states outside of closed atomic shells in alkali metals, were populated by the (Be9, Be8) one-neutron transfer reaction in inverse kinematics using particle-γ coincidence s

One-neutron transfer study of 135Te and 137Xe by particle-γ coincidence spectroscopy: The ν1i13/2 state at N = 83

Additional information is reported on single-neutron states above the doubly closed-shell nucleus 132Sn. A radioactive ion beam of 134Te(N=82) at 565 MeV and a stable ion beam of 136Xe(N=82) at 560 MeV were used to study single-neutron states in the N=8

On the origin of low-lying M1 strength in even-even nuclei

The 2+2 state in132Te is identified as the one-phonon MSS in a projectile Coulomb excitation experiment presenting a firm example of a MSS in unstable, neutron rich nuclei. The results of shell-model calculations based on the low-momentum interaction Vlow-k are in good agreement with experiment demonstrating, the ability of the effective shell-model interaction to produce states of mixed symmetry character

g-Factor Measurements of First 2 + States of Heavy Te Isotopes Based on Nuclear Spin Deorientation for Nuclei Recoiling in Vacuum

We demonstrate that the recoil-in-vacuum (RIV) method can be used to determine the g-factor of the Coulumb excited first 2+ state of 132Te. This was possible owing to advantages provided by CLARION (ORNL clover multi-detector array) and the segmented charged particle detector HyBall. Calibratory experiments were performed with 122,126,130Te and a g-factor of 132Te was deduced g = (+)0.35(5)

One-phonon isovector 2 + 1,MS state in the neutron rich nucleus 132 Te

The 22+ state in132Te is identified as the one-phonon MSS in a projectile Coulomb excitation experiment presenting a firm example of a MSS in unstable, neutron rich nuclei. The results of shell-model calculations based on the low-momentum interaction Vlow-k are in good agreement with experiment demonstrating the ability of the effective shell-model interaction to produce states of mixed-symmetry character
