Binding of a 3He Impurity to a Screw Dislocation in Solid 4He
Based on simulation the probability density solid atom the nucleus
2014/12/19
Using first-principles simulations for the probability density of finding a 3He atom in the vicinity of the screw dislocation in solid 4He, we determine the binding energy to the dislocation nucleus E...

2010/11/19
We present a free energy functional for superfluid 3He in the presence of homogeneously distributed impurity disorder which extends the Ginzburg-Landau free energy functional to all temperatures. We u...
The differential and total cross-sections for the dp \to 3He \eta reaction have been measured in a high precision high statistics COSY-ANKE experiment near threshold using a continuous beam energy ram...

Frame dependence of 3He transverse (e,e') response functions intermediate momentum transfers
2011/1/7
The transverse electron scattering response function of 3He was recently studied by us in the
quasi-elastic peak region for momentum transfers q between 500 and 700 MeV/c. Those results,
obtained us...

2009/6/9
将R.Crespo和J.A.Tostevin提出的方法,推广应用于自旋的散射,研究了p—3He弹性散射动量空间库仑作用的处理.计算了200—500MeV的微分散射截面和自旋观测量,并将其结果与V—P方法所得结果及实验结果进行了比较,显示出这种方法与V—P方法相比可应用的角动量和动量转移的范围更宽些.

2009/6/9
以p-3He弹性散射为例,应用C.M.Vincent和S.C.Phatak提出的方案,研究了动量空间库仑作用的处理.计算了200—500MeV的微分散射截面和自旋观测量,所得结果表明库仑作用仅在动量转移q<3.5fm－1的区域产生较小的影响.
关於2H,3H,3He,4He诸原子核结合能之问题——第一部
2007/12/12
我们应用变分法,以摩勒—罗森费德之原子核位能为基础,计算2H,2H,3He,4He诸原子核之结合能。因所选之波函数简单,计算很容易。计算结果与实验所得结果符合,惟4He之结合能过大,指明所采用之原子核位能尚须加以修改。
关於2H,3H,3He,4He诸原子核结合能之问题——第二部
2007/12/12
在这里我们证明,应用摩勒—罗森费德之原子核位能公式,以286倍电子质量为介子之质量,来计算3H,4He之结合能,所得之结果与实验结果间之差异,虽经修改波函数,仍不能补救。
关於2H,3H,3He,4He诸原子核结合能之问题——第三部
2007/12/12
本文仍用根据介子学说之位能,但除去其与电荷无关之假定,来研究2H,3H,3He,4He诸原子核结合能之问题。初步计算所得结果指明,核子与中性介子场之作用不含有r3因子,又中性介子之质量略大於带电介子之质量。
