我们在描述一个宏观球体的时候,经常采用半径来表示它的大小。在原子核物理中也是用“核半径”来表示原子核的大小的。但是应当注意,由于原子核很小,直到目前仍无法直接观察到它,那么它的半径也就无法“量”出来了,而只能通过实验间接地计算出。所以,“核半径”不同于宏观球体的半径,它并不是指原子核的几何半径。在对原子核进行研究的早期,它是指核的密度分布范围。后来,当人们发现原子核也是有内部
When we describe a macrosphere, we often use radius to indicate its size. In nuclear physics, the “nuclear radius” is also used to indicate the size of the atomic nucleus. However, it should be noted that since the nucleus is very small, it cannot be observed directly until now, then its radius cannot be “measured” and can only be calculated indirectly through experiments. Therefore, the “nucleus radius” is different from the radius of the macrosphere. It does not refer to the geometric radius of the nucleus. In the early days of research on atomic nuclei, it was referring to the nuclear density distribution. Later, when people discovered that the nucleus also has internal
