被引用回数:38 パーセンタイル:84.92(Instruments & Instrumentation)A highly efficient array of high-purity germanium (HPGe) detectors was developed and operated at the cold neutron beam facility PF1B of the Institut Laue-Langevin (ILL) to carry out nuclear structure studies, via measurements of -rays following neutron-induced capture and fission reactions. The setup consisted of a collimation system producing a pencil beam with a thermal capture equivalent flux of about 10nscm at the target position and negligible neutron halo. The target was surrounded by an array of eight to ten anti-Compton shielded EXOGAM Clover detectors, four to six anti-Compton shielded large coaxial GASP detectors and two standard Clover detectors. For a part of the campaign the array was combined with 16 LaBr:(Ce) detectors from the FATIMA collaboration.

周期表第4族に属するZr,Hf並びに超アクチノイド元素Rfの塩酸溶液からトリブチルリン酸(TBP)への抽出挙動を調べた。8M HCl/TBP系においてZr, Hf, Rfそれぞれの分配係数は1180, 65,150となりTBPへの抽出はHfRfZrの順で大きくなるという興味ある結果が得られた。これは元素の周期性だけからは説明できない。したがって、相対論効果を考慮した理論計算に、加水分解と錯形成間の競争過程を導した計算を行うと実験の傾向をよく再現できることがわかった。
