Particle beam
|
A thin stream of particles such as atoms, molecules, ions, atomic nuclei, neutrons, and electrons moving in a certain direction. It is used to measure magnetic moments, collision cross sections (collisions), etc., and is important in the study of atomic nuclei. In addition, particles have wave properties and diffract like X-rays when they hit matter, so the diffraction of electron beams and neutron beams in particular is used in the study of material structure. → Related topic Absorption (physics) Source : Heibonsha Encyclopedia About MyPedia Information |

原子，分子，イオン，原子核，中性子，電子などの粒子が一定方向に向かう細い流れ。磁気モーメント，衝突断面積（衝突）等の測定に使われ，原子核の研究に重要。また粒子は波動性をもち，物質に当たってＸ線と同様に回折を起こすので，特に電子線，中性子線の回折を物質構造の研究に使う。 →関連項目吸収（物理） 出典 株式会社平凡社百科事典マイペディアについて 情報 |
