查询词典 isotopes

The ground states properties of Ne-isotopes were calculated with Relativistic mean field theory. Compared with the experimental datas, its discovered that the nucleus properties chang regularly with the changes of neutron number when the proton number is even. The results proved indirectly that even nucleus has no direct influenced on another kind of nucleus. Besides, the applicability of Relativistic mean field theory in this region was tested.

用相对论平均场理论计算了Ne同位素的基态性质，并和实验比较，发现当质子是偶数时，核的性质有规律地随中子数的变化而变化，由此间接证明了偶数核子对另一类核子无直接影响；同时，也检验了相对论平均场理论在该区域的适用性。
