Determination of trace elements using multi-parameter coincidence spectrometry

Hatsukawa, Yuichi; Toh, Yosuke; Oshima, Masumi; Kimura, Atsushi; Gharaie, M. H. M.

Journal of Radioanalytical and Nuclear Chemistry, 271(1), p.43 - 45, 2007/01

 Times Cited Count：3 Percentile：25.51(Chemistry, Analytical)

$$gamma$$-$$gamma$$ coincidence of multiple $$gamma$$-rays from the radioisotopes produced by neutron capture reactions was measured with a array of 19-Ge detectors with BGO Compton suppressors, GEMINI-II. Using multiparameter spectrometry, high sensitive determination of iridium in geological samples and I-129 in environmental samples were carried out at GEMINI.

Multiple coulomb excitation experiment of $$^{68}$$Zn

Coulomb excitation experiment was carried out with a $$^{68}$$Zn beam bombarding a $$^{nat}$$Pb target. Two $$E2$$ matrix elements and the quadrupole moment of the 2$$_{1}$$$$^{+}$$ state were newly derived with the least-squares search code GOSIA. The potential energy surface (PES) was calculated with the Nilsson-Strutinsky model, showing two shallow minima: the first minimum does not contain the $$1g_{9/2}$$ orbit below the Fermi surface, while the second minimum does. The ground state band and the intruder band seem to be constructed on the first and the second minimum, respectively. As for the ground state band, the asymmetric rotor model and the IBM in O(6) limit reproduced the experimental values rather well. The shallow PES may suggest unstability of the shape. The ground state band structure may be explained assuming a soft triaxial deformation.
