摘要
汤川秀树是日本著名的理论物理学家 .1935年 ,汤川秀树在物理学界普遍不接受新粒子的情况下 ,大胆提出一种新的核力场理论 ,认为存在起强相互作用的π介子 .介子理论的提出 ,推动了核物理研究的发展 .文章简要记述了这一历史事件 .在介子理论提出 10年后 ,π介子才被英国物理学家鲍威尔在宇宙射线中发现 ,证实了汤川秀树的假设 .由于汤川秀树对物理学发展所作出的贡献 ,汤川秀树获得 1949年诺贝尔物理奖 .
In 1935 Hideki Yukawa courageously proposed a new field theory of the nuclear forces and predicted the existence of the meson, a particle responsible for the strong interaction. This was during a period when new particles were not welcomed in the domain of physics. Later, the meson theory greatly promoted the advancement of nuclear physics. The theory was verified after the π meson was discovered in cosmic rays by C.P.Powell, a British physicist. Yukawa was awarded the Nobel Prize in 1949 for his contribution to physics.
