这里的Gamma不是指Gamma点, 而是在计算时k空间的自动产生k点的取点方式,有Gamma和Monkhorst, 前一种以Gamma点为中心,贴上说明书的片段吧 QQ截图20140213114206.png beefly 6楼: Originally posted by xhzha at 2014-02-13 11:43:12 这里的Gamma不是指Gamma点, 而是在计算时k空间的自动产生k点的取点方式,...

一、空晶格模型得到的能带和倒格子在Gamma点的关系为 然后把它用到Gamma点 (Td point group) (1,1,1) level得到了两个三重简并的表示,如上能带图中所标。三重简并的表示即六重简并的能级。其具体的能级分布,由轨道相互作用决定,具体问题得具体分析。同样也可以分析其他高对称点的性质。。。 二、滑移面和...
Gamma(x|\alpha=k+1)=\frac{x^{k}e^{-x}}{\Gamma(k+1)}=\frac{x^{k}e^{-x}}{k!}\\ 可以看到这两个分布在数学形式上是一致的,只是Poisson分布式离散的,Gamma分布式连续的,可以直观认为,Gamma分布式是Poisson分布在正实数集上连续化版本。 我们在概率论与数理统计的课程中都学过, Poisson(\lambda...
Ideally, the flux of photons arriving at a radiation detector would be proportional to the number of photons emitted in the respective part of the body being imaged. This assumption would be valid only if the body part were a point source of radiation in air, which is clearly never the cas...

1, which shows the point source sensitivity of COMPTEL compared to that of past, present, and future instruments in neighboring energy bands. The “sensitivity gap” from 0.5 to 50 MeV is evident. Although the IBIS and SPI instruments on INTEGRAL cover some of the medium-energy band, these ...
