“…Gyromagnetic-ratio measurements on excited states of radioactive beams are challenging and the number of cases studied to date is limited [10][11][12][13][14][15]. The techniques used successfully are the conventional transient-field (TF) method at "low" ion velocities [10,15], recoil in vacuum (RIV) [11,14], and high-velocity transient field (HVTF) [12,13].…”

The high-velocity transient-field (HVTF) technique was used to measure the g factor of the 2 + state of 72 Zn produced as a radioactive beam. The transient-field strength was probed at high velocity in ferromagnetic iron and gadolinium hosts using 76 Ge beams. The potential of the HVTF method is demonstrated and the difficulties that need to be overcome for a reliable use of the TF technique with high-Z, high-velocity radioactive beams are revealed. The polarization of K-shell vacancies at high velocity, which shows more than an order of magnitude difference between Z = 20 and Z = 30 is discussed. The g-factor measurement hints at the theoretically predicted transition in the structure of the Zn isotopes near N = 40.

“…The RIV technique has proved to be a powerful method to measure the g factors of excited states of neutron-rich nuclei produced as radioactive beams, particularly in the tin and tellurium isotopes near the neutron-rich doubly magic nuclide 132 Sn [12][13][14][15][16]. One of the method's advantages is that the g factor of the 2 + 1 state can be measured simultaneously with the B(E2; 0 + → 2 + ) and Q(2 + ) [14][15][16][17][18].…”

First-excited state g factor of Te136 by the recoil in vacuum method

The g factor of the first 2 + state of radioactive 136 Te with two valence protons and two valence neutrons beyond double-magic 132 Sn has been measured by the Recoil in Vacuum (RIV) method. The lifetime of this state is an order of magnitude longer than the lifetimes of excited states recently measured by the RIV method in Sn and Te isotopes, requiring a new evaluation of the free-ion hyperfine interactions and methodology used to determine the g factor. The calibration data are reported and the analysis procedures are described in detail. The resultant g factor has a similar magnitude to the g factors of other nuclei with an equal number of valence protons and neutrons in the major shell. However, an unexpected trend is found in the g factors of the N = 84 isotones, which decrease from 136 Te to 144 Nd. Shell model calculations with interactions derived from the CD Bonn potential show good agreement with the g factors and E2 transition rates of 2 + states around 132 Sn, confirming earlier indications that 132 Sn is a good doubly magic core.

“…The method has been shown, in an experiment on the first 2 + state of 132 Te, to offer attractive possibilities for application with relatively weak radioactive ion beams [RIBs] when combined with modern detector arrays [1]. In that measurement the magnetic hyperfine interaction acting on the nuclei of the recoiling ions was calibrated using 2 + states of other Te isotopes having known lifetime and g-factor.…”
