The heavy elements in the theory of spontaneous metamorphosis immediate sensation around the world ;(4) is proposed to estimate the Earth's radiation age;(5) from the charge-mass ratio α which is derived helium ions;(6) from the scattering of α Bighorn recognized atomic mass concentrated in a radius of 10-12 meters in the nuclear, on positively charged core surrounded by negatively charged electrons;(7) with natural α-particles from the nitrogen nuclei in the outgoing protons, this is the first time human beings to change the chemical elements of artificial nuclear reactions;(8) predicted that heavy hydrogen and neutron sub-existence .

这一重元素自发蜕变理论立即轰动全世界；（4）提出用放射性估算地球年龄；（5）从α的荷质比得出它是氦离子；（6）从α大角散射认识到原子质量集中在半径为10－12米的核上，核带正电，周围是带负电的电子；（7）用天然α粒子从氮原子核中打出质子，这是人类第一次实现改变化学元素的人工核反应；（8）预言重氢子和中子存在。

Accelerators are used to study the structure of atomic nuclei and the nature of subatomic particle s and their fundamental interactions.

加速器用来研究原子核的结构，亚原子粒子的性质及其基本相互作用。

The most common isotope of oxygen, for example, has an atomic weight of 16, but there are also rarer isotopes with weights of 17 and 18, caused by additional neutrons in their nuclei.

例如很常见的同位素氧，原子重量是16，但是还有更为稀少的重量为17和18的同位素，这是因为它们的原子核中有额外的中子。

The purpose of this thesis is to study the high-spin states in atomic nuclei.

本论文工作的目的是研究原子核的高自旋态特性。
