First $$alpha$$-$$gamma$$ spectroscopy using Si-Ge detector array installed at focal plane of GARIS

Kaji, Daiya*; Morimoto, Koji*; Wakabayashi, Yasuo*; Takeyama, Mirei*; Asai, Masato

JPS Conference Proceedings (Internet), 6, p.030106_1 - 030106_4, 2015/06

A Si-Ge detector array was newly installed at the focal plane of the gas-filled recoil ion separator GARIS to perform $$alpha$$-$$gamma$$ (X-rays) spectroscopy for superheavy nuclei. The performance of the array was tested using the $$^{207}$$Pb($$^{48}$$Ca,2n)$$^{253}$$No and $$^{208}$$Pb($$^{48}$$Ca,xn)$$^{256-x}$$No [x=1,2,3] reactions. $$gamma$$ rays originating from the $$alpha$$ decay of $$^{253}$$No and $$^{255}$$No were clearly observed in prompt coincidence with the $$alpha$$ particles.

Performance of new gas-filled recoil ion separator GARIS-II for asymmetric fusion reaction

Kaji, Daiya*; Morimoto, Koji*; Wakabayashi, Yasuo*; Takeyama, Mirei*; Yamaki, Sayaka*; Tanaka, Kengo*; Haba, Hiromitsu*; Huang, M.*; Murakami, Masashi*; Kanaya, Jumpei*; et al.

JPS Conference Proceedings (Internet), 6, p.030107_1 - 030107_4, 2015/06

https://doi.org/10.7566/JPSCP.6.030107

Performance of the new gas-filled recoil ion separator GARIS-II was investigated using asymmetric $$^{22}$$Ne-induced fusion reactions. The use of He-H$$_{2}$$ mixture gas for the gas-filled magnet significantly reduced background scattered particles detected at the focal-plane Si detector, and increased a transmission of the asymmetric reaction products. A target-identification system was newly installed for efficient measurements of excitation functions without changing beam energy nor target.
