- ItemNuclear structure studies relevant to ¹³⁶Xe ββ decay(IOP Publishing, 2018) Rebeiro, B. M.; Triambak, S.; Garrett, P. E.; Lindsay, R.; Adsley, P.; Ball, G. C.; Bildstein, V.; Burbadge, C.; Diaz-Varela, A.; Faestermann, T.; Hertenberger, R.; Jigmeddorj, B.; Kamil, M.; Leach, K. G.; Mabika, P. Z.; Nzobadila, J. C.; Orce, J. N.; Radich, A. J.; Rand, E.; Wirth, H. F.In these proceedings we briefly discuss preliminary results from ¹³⁸Ba(d, α) and ¹³⁸Ba(p, t) reactions performed using the Q3D magentic spectrometer at the Maier-Leibnitz- Laboratorium (MLL) tandem accelerator facility in Garching, Germany. Our results aim to provide useful spectroscopic information for the calculation of the ¹³⁶Xe →¹³⁶ Ba double beta decay matrix elements.
- ItemSpectroscopy of low lying states in 136Cs(IOP Publishing, 2016) Rebeiro, B.; Triambak, S.; Lindsay, R.; Adsley, P.; Burbadge, C.; Ball, G.; Bildstein, V.; Faestermann, T.; Garrett, P. E.; Hertenberger, R.; Radich, A.; Rand, E.; Varela, A.; Wirth, H.-F.The low-lying excited states in 136Cs relevant to the double beta decay of 136Xe were studied via a 138Ba(d, α)136Cs transfer reaction with a high resolution magnetic spectrometer. Preliminary results from the experiment are presented.
- ItemSpectroscopy of low-spin states in 157Dy : Search for evidence of enhanced octupole correlations(American Physical Society, 2019) Majola, S. N. T.; Bark, R. A.; Bianco, L.; Bucher, T. D.; Bvumbi, S. P.; Cullen, D. M.; Garrett, P. E.; Greenlees, P. T.; Hartley, D.; Hirvonen, J.; Jakobsson, U.; Jones, P. M.; Julin, R.; Juutinen, S.; Ketelhut, S.; Kheswa, B. V.; Korichi, A.; Lawrie, E. A.; Masiteng, P. L.; Maqabuka, B.; Mdletshe, L.; Minkova, A.; Ndayishimye, J.; Nieminen, P.; Nyako, B. M.; Peura, P.; Rahkila, P.; Riedinger, L. L.; Riley, M.; Roux, D.; Ruotsalainen, P.; Saren, J.; Sharpey-Schafer, J. F.; Scholey, C.; Shirinda, O.; Sithole, A.; Sorri, J.; Stolze, S.; Timar, J.; Uusitalo, J.; Zimba, G.Low-spin states of ¹⁵⁷Dy have been studied using the JUROGAM II array, following the ¹⁵⁵Gd (α, 2n) reaction at a beam energy of 25 MeV. The level scheme of ¹⁵⁷Dy has been expanded with four new bands. Rotational structures built on the [523]5/2⁻ and [402]3/2⁺ neutron orbitals constitute new additions to the level scheme as do many of the inter- and intraband transitions. This manuscript also reports the observation of cross I⁺ →(I–1) ⁻ and I⁻ →(I–1)⁺ E1 dipole transitions interlinking structures built on the [523]5/2⁻ (band 5) and [402]3/2⁺ (band 7) neutron orbitals. These interlacing band structures are interpreted as the bands of parity doublets with simplex quantum number s=–i related to possible octupole correlations.
