查询词典 proton

The theoretical prediction of large energy gap exists near the neutron number~44 and proton number~38-40 are also compared and discussed.

许多理论预测在中子数N~44，而质子数Z~38-40 附近，存在大的能隙，而我们研究的几个原子核，其核子数恰好位在此能隙附近，所以文中也针对此变形位障所预测的幻数加以讨论。

At the same time, the neutrons and protons are excited to be emitted with the same probability for Pauli potential, momentum dependence interaction and impact parameter, even though their effects on preequilibrium neutron number and proton number are obvious.

故从低能量到较高能量的较大能区内，前平衡发射的中子-质子比的理论值与实验值的比较是提取对称势形式和强度的灵敏探针。

It is shown, for the first time, that the pairing strength of the neutron, Gn, increases dramatically around the magic number N=82, while for the proton it is strongly related to the odd-even difference of the neutron number.

在相对论平均场框架下系统地研究了稀土区同位素链的对力强度，首次发现了中子的对力强度 Gn在中子幻数N=82处突然增大以及质子的对力强度 Gp和中子的奇、偶性有关的特性，证明了对力强度本质上是和核的壳层结构紧切相关。

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。

The NIEL induced by low energy proton in Si and GaAs have been calculated using analytical method and Monte-Carlo code. Thin_target approximation was used when calculating NIEL by SRIM code and the result compared with that of other authors'. The results show that thin_target approximation is reasonable and NIEL scaling is feasible. The NIEL values become lower after taking into account the screening effect.

为此，本文采用解析法和基于Monte-Carlo方法的SRIM程序计算了考虑库仑屏蔽效应后低能质子在半导体材料Si，GaAs中的NIEL，SRIM程序在计算过程中采用薄靶近似法，并与其他作者的计算数据和实验数据进行了比较。
