Outline of Annual Research Achievements

本研究では，新元素の合成に用いられる理研気体充填型反跳核分離装置に，高周波カーペットガスセルとSi半導体検出器から構成される超高速低温ガスクロマトグラフ装置を開発することによって，超重元素（原子番号104以上）の気相系における化学的性質を単一原子レベルで解明するための新しい化学元素分析システムを開発している．今年度は，高周波カーペットガスセルと高周波四重極イオンガイドから構成される超重元素イオン収集装置を製作し，性能評価を進めた．ガスセルに入射した高エネルギーのイオンは，Heガスとの衝突により減速され，DC電圧勾配によりRFカーペットまで素早く運搬される．RFカーペットにはイオンバリア用の高周波電圧とイオン輸送用の低周波電圧が印可され，イオンをロスなくカーペット中心の穴（直径0.3 mm）まで運搬できる．穴から出たイオンは，高周波四重極イオンガイドにより低速・小径のイオンビームとして高真空中へ運搬される．装置の性能評価として，ガスセル内のイオン源からCsイオンを引き出す実験を行った．DC電圧勾配，高周波電圧，低周波電圧などの条件を最適化し，100%に近い効率でCsイオンを引き出すことに成功した．また，加速器実験を模擬して，Ra-224線源から高エネルギーで飛び出してくるRn-220イオンを引き出す実験を行い，10 ms程度の短い時間でRn-220イオンを引き出せることを確認した．本システムにより，化学装置までの壊変ロスを最小限に抑え，ニホニウム同位体Nh-284の収率を飛躍的に増大できる見込みである．また，今年度は，低温ガスクロマトグラフカラムを構成する大面積Si半導体検出器と前置増幅器の製作，性能試験を行った．さらに，前置増幅器から出力されたパルス信号の生波形をそのまま記録し，Nh-284を確度良く定量するために必要な16 chデジタルパルスプロセッサを調達した．

Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

理研重イオン線形加速器の増強工事が当初の予定よりも遅れているため．

Strategy for Future Research Activity

超重元素の気相化学分析を行うため，超高速低温ガスクロマトグラフ装置を開発し，昨年度開発した高周波カーペットガスセルに結合する．ガスクロマトグラフカラムは昨年度製作した32対の大効率Si半導体検出器で構成し，カラム末端を液体窒素で冷却し，室温から液体窒素温度付近まで温度勾配をかける．本研究で対象とするニホニウム（Nh），コペルニシウム（Cn）ならびにフレロビウム（Fl）は，強い相対論効果の影響で電子構造が閉殻構造となり，常温で希ガス元素ラドン（Rn）のように気体となり，化学的不活性を示すことが予測されている．カラム内に入った単体原子は，カラム固定相と吸脱着相互作用を繰り返しながらアルゴンガスとともにカラム内を進む．単体原子が吸着し，アルファ壊変または自発核分裂壊変した検出器位置から元素固有の収率分布を得ることができる．最終的に，収率分布をモンテカルロシミュレーションし，超重元素の固定相に対する吸着エントロピーを導出する．低温ガスクロマトグラフ装置の性能試験は，アルファ粒子放出核種であるRn-219をアルゴンとともに高周波カーペットガスセルに導入して進める．2021年度以降のNh，CnならびにFlの化学実験に向けて，これら元素の軽い同族元素の既知の化学的性質や相対論的量子化学計算の予測などを参考とし，超高速低温ガスクロマトグラフ装置のパラメーター（ガス圧，ガス流量，カラム温度など）を最適化する．本研究では，超重元素RIの合成から化学分離まで，所要時間1秒以内の超高速ガスクロマトグラフィーを目指す．さらに，2020年度は，GARISの焦点面に位置有感型の箱型Si半導体検出器を設置し，Am-243 + Ca-48 → Mc-288 + 3n反応によって115番元素Mc-288の合成を試みる．2021年度以降，Mc-288が半減期164 msで瞬時にα壊変して生成するNh-284を化学実験に用いることを計画している．
