...In other words, a nucleon does not exert nuclear forces on all nucleons in a nucleus, but only on a few nucleons nearby. This is the saturation of nuclear force. Heisenberg thought that saturation was due to the property of exchange forces, but in reality, there is a region called a hard core in the short distance between two nucleons, and nucleons cannot approach each other within a certain distance, creating a substance with a constant density. ... *Some of the terminology explanations that refer to "saturation of nuclear forces" are listed below.

…すなわちある核子は核内のすべての核子と核力を及ぼし合うのでなく,近くの数個の核子とのみ引き合っているのである。これが核力の飽和性saturation of nuclear forceである。ハイゼンベルクは飽和性は交換力という性質によるものと考えたが,実際は2核子の短距離部分に固い芯と呼ばれる領域があり,核子どうしがある距離以内に近づくことができず,密度一定の物質をつくるためである。… ※「核力の飽和性」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
