Research Abstract

A03計画研究は2つの方向に大別される。すなわち(A)高速放射性イオンを用いた新しいプローブの開発と(B)高速放射性イオンをプローブとした物質化学の研究である。プローブ法の開発としては,(A1)イオントラップとレーザーを組み合わせて蓄積した^9Be^+のレーザー冷却を行い、結晶化が観測された。また^9Be^+の1イオンについてレーザーマイクロ波の二重共鳴が成功している。現在不安定核^7Be^+(半減期53日)の実験が進行中であるが、これは^7Beの磁気モーメント測定、磁化分布の測定を目指しており、物質中のBe^+プローブとして有効な核データを提供する。また(A2)化合物半導体InPの動的自己核偏極が成功し、未知核種について汎用性の高い偏極ストッパーとして用いる開発をすすめている。また(A3)ポジトロニウムの崩壊位置を2台の2次元位置有感型のガンマ線検出器を用いて得られた3.5mmの分解能が40x45mm^2の領域について線型性があることが調べられた。(B)の物質化学の研究では、まず(B1)^8Li、^9C、^<19>O、^<23>Mg等の不安定核を結晶内に埋め込み、磁気モーメント、電気4重極モーメント、ナイトシフト、超微細相互作用について研究を行った。また(B2)α-Feの点欠陥の挙動を^<140>Ce核をプローブとして研究し、また100MeV^<40>Arビームにより^<57>Fe膜からのクローン励起反跳打込みメスバウア分光を行っている。また(B3)ISOLにより^<111>Inを試料に打込み摂動角度相関(PAC)法により予め打込んである、As、Sb、Se、Fe等の不純物との再結合センターの形成の研究を行った。
