Hello all,
I have a basic question with the theta-2theta technique in XRD. Here it is:
If I have a single crystal material and I perform the above mentioned characterization. Should I get one diffraction peak associated to the orientation of the bulk crystal or should I get many peaks...
Hello,
1) I am trying trying to simulate a laser scattering experiment in Mathematica. So the first trouble I have is how to define a set of 3D points. I did this program in C++ like this:
for (int i=0; i<3; i++)
{
pyr[0].point[0][i]=0;
}
for (int a=1; a<3; a++)
{
for (int b=0; b<3...
I have a question if anyone can answer this. I wrote down the equation for a plane in the post above. But what happens is that if I keep Theta = 0, any changes in Phi and R are not displayed, i.e., there is no effect if I change either one of them. But if I have a non-zero Theta, the changes in...
Thanks a lot for your help. I went along with what you suggested and made some changes to go along. Here is the code that I did.
Manipulate[
Plot3D[z = (-Cos[\[Phi] Degree] Sin[\[Theta] Degree] x -
Sin[\[Phi] Degree] Sin[\[Theta] Degree] y +
r Sin[\[Theta] Degree]...
Hi,
I am trying to draw a plane that is normal to a given vector. I want to enter to the normal in polar coordinates so that I can manipulate the Theta and Phi and see how various planes cut the (111) planes in silicon crystal. Help would be much appreciated.
Thanks in advance
Cheers
Hi,
I am trying to calculate the time evolution of a density matrix. Like if there is a mixed state with 50% of |x, 0> and 50% of |y, 0>. After time t due to time evolution, the kets become:
|x,t>= e^(-i/h Ht) |x,0> and so on.
Is it ok to use these kets instead of the original ket to...
Hi,
I just came across a question that goes like this:
Consider an electron in a state |l=3, s=1/2, j=5/2,mj=3/2>
1) Find the possible values of Lz in this state.
2) Find the expectation value of Lz in this state.
It would be great if some one could guide with this question.
Thanks
