Research Abstract	μ粒子触媒核融合では[(dtμ)dee]の働起エネルギーの計算が重要である。島村(理研)、上村(九大)らはこのエネるギーの補正項である(dtμ)コアのサイズ効果の精密計算を行い従来よりもこの効果の大きいことを示した。原(筑波短大)とArmerらは[(dtμ)dee]のオージェ効果よるに安定化過程の粘密計算を行った。上村(九大)は木野の協力を得てtd中にある不純物Heへμ粒子が移行反応するときに重要な役割を果すd^4Heμとd^3Heμの放射性脱働起と解離性脱働起を木野の開発した新しい方法で計算した。これは永嶺らのX線の測定による実験結果とより一致を見た。福島(都立大)は固体水素中のμ触媒反応の研究を行い、スペクトル分布を調べることにより凝縮効果を解明した。pHe^+については佐々木グループ(北大)の大槻らにより分解原子コアモデルによる計算を行い、山崎(東大.核研)らとカスケード活過程についての評価を行った。島村(理研)は同じ問題をボルン・オボンパイマー近似で定式化して、この分子の活性質を計算した。前述の分極原子コアモデルについての再検討を行った。石原、戸嶋(筑波)らはTDCW法を用いてポジトロニラム生成反応の理論的解明を行った。また低エネルギーでは超付度係法による計算を行った。赤石(東大、核研)はストレンジネスを持った負電荷の粒子がつくる原子について、そのカスケード過程と粒子が核と吸収された後の現象を調べた。鳴海(福山大)はK中間子原子とおける2核子吸収過程について翁長と調べた。渡部(ICU)は大崎の協力を得て任意の質量比のクローン3体問題についての古転S行列法の適用考えて定式化を行った。実験グループ、山崎(東大原子核研)と永嶺(東大理,理研)はそれぞれpHeとμCFの実験を行い理論グループにホットを実験結果を提供した。そのあるものは計算された。あるものは将来の研究にゆだねられている。
