[N2]*2-N2分子二聚物的发射谱和受激辐射特性

理论上通过从头算法计算与理论分析证明存在D_2h群对称性的[N₂]₂即N₂分子二聚物，且存在电偶极允许的类准分子跃迁a¹B_2g→a¹B_3u. 理论计算获得的a¹B_2g→a¹B_3u跃迁的发射谱与实验观测到的结果很好地吻合. 利用微波激励高纯氮和放大自发辐射法研究了N₂分子二聚物的受激辐射特性，实验研究结果表明，当微波功率大于100 W，充入N2气压在260~2200 Pa范围内N₂分子二聚物在336.21 nm处存在受激辐射特性.

Magnetostriction Dependence of the Relaxation Frequency in the Magnetoimpedance Effect for Amorphous and Nanocrystalline Ribbons

The magnetoimpedance effect and changes of the relaxation frequency fx are studied in CoFeSiB and CoFeMoSiB amorphous and FeCuNbSiB nanocrystalline ribbons.The evolution of the magnetostriction constant λs and relaxation frequency is analysed for the states with different magnetic anisotropies induced in the same ribbons.A monotonic decrease of the relaxation frequency is observed for shifting of λs towards positive values.

基于平移不变壳模型的轻核(A≤6)基态特性

包含中心力、张量力、自旋-轨道力和四级自旋-轨道力且具有高斯型径向关系的唯象核子-核子相互作用被构造并通过调节有关参数来得到氘核结合能、均方根半径、D态几率、磁偶极矩和电四极矩的理论值和实验值之间的最好拟合.氘核基态波函数用对应主量子数0≤N≤1 0的平移不变壳模型基函数来展开.另外,用新的相互作用还计算了³H ,⁴He,⁵He和⁶Li核的结合能、均方根半径和磁偶极矩.这些核的波函数也是用平移不变壳模型基函数来展开,只是对前两个核,N=10;对⁵He,N=7;对⁶Li,N=6.对氘核,进一步研究了三体力的作用.所得结果与相应的实验数据符合甚好.
