グランドライデン・スペクトログラフは世界最高の運動量分解能 (D/M=37,000)を有しており、大口径スペクトログラフLASと組み合わせた2アームスペクトログラフシステムとして使用することで、原子核のスピン・アイソスピン応答の研究や、クラスター状態の探索などの高分解能・高精度核分光研究を推進しています。 高分解能ビーム分析ラインと組み合わせて運動量分散整合技術を用いることでビームの分解能以上の励起エネルギー分解能が得られ、 300MeVの陽子に対して15KeVの分解能を達成しています。 焦点面偏極度計を備えており、効率3%、有効偏極分解能40%で 陽子の偏極を測定することができます。 LASの角度アクセプタンスは20msrと大きく、単独で大口径を必要とする測定に利用する他、グランドライデンと組み合わせることで（p,2p)同時計測を行うこともできます。 技術的な詳細は以下の文献をご覧下さい。

酸素-16原子核中のテンソル力
原子核内の陽子・中性子間に働くテンソル力は重水素及びアルファ粒子の束縛エネルギーに大きく寄与する等、原子核において重要な役割を担っていることが知られています。にもかかわらず、原子核におけるテンソル力の効果はアルファ粒子までの軽い原子核を除いて、実験による直接的な証拠が報告されていません。我々はテンソル力による軽い原子核の核構造への寄与を調べるために、大阪大学核物理研究センターにて16O(p,d)反応実験を行いました。実験の結果、16Oの基底状態においてsd-軌道を占有すると考えられる高運動量中性子が予想以上に存在することが明らかになりました。我々は高運動量成分を含むようなガウス基底関数を用いた単純な計算から、本実験の結果がテンソル力効果による可能性があると結論付けました。 Referrence [1] H.

鉛-208原子核の電気双極子応答の完全測定
陽子非弾性散乱の超前方測定により、208Pbの電気双極(E1)応答を精密に決定した。得られたE1遷移強度分布はピグミー双極共鳴の研究にとって重要であるほか、和則値を引き出す目的で使用することができる。特に励起エネルギーの逆数を重みとする和則値である双極分極率は、中性子スキンの厚さや状態方程式の対称エネルギーの密度依存性と強い相関をもつ量として注目されており、中性子星の性質や超新星爆発過程、元素合成過程などの決定に重大な意義を持つ。
