Ok, this starts to make sence. I figured that S only have M_j = 0, which means that the're only 2 transmissions, so I calculated the difference to E_ZE(M_j = 1) - E_ZE(M_j = -1) and got delta f = 8.398GHz, which I've got confirmed is right.
but they ask for the wavelength difference, so...
You tell me.
When I look in my formula sheet I find.
"For weak fields, hfs:
E_ZE = g_F * my_B * B * M_F"
I suppose that E_ZE is the energy separation? But I don't see how I can calculate g_F, since it contains the nuclear spin I, which I don't have. And I'm not even sure if that's the...
Over a He-lamp a weak vertical magnetic field ( B = 300mT) is beeing applied. The light from the lamp is beeing studies with a high resolution spectrometer in the direction of the B-field. What will the wavelength difference between the observed Zeeman components be in the transmission 1s2p 1P -...
1. Determine all terms in the configuration 4s^2 4p 4d in neutral germanium
The answear is
Singlett P,D and F
Tripplett P,D and F
But I don't really understand what singlett and tripplett means, and how do I know which tearms there are?
Not sure if this should be in this forum, but let's try.
The problem is about 2 samples. One pure Na and one InSb.
I want to determine the hall voltage when we send a current of 100mA trough the samples and the magnetic field is B = 0.1T. The samples are dimensioned "squared" 5x1x5mm. We...
Since I couldn't get this right I did some backwards calculating. I have parts of a solution given, and there I could find the real value for N_e. And reverse engineering gave me that E_f = 0.16eV, whick is the given acceptor level for indium. This puzzles me since I tought the fermi energy...
A sample of silicon is doped with indium for which the electron acceptor level is 0.16eV above the top of the valence band. What impurity density would cause the fermi level to coincide with the impurity level at 300K? What fraction of the acceptor levels is then filled? What are the majority...
ok, so in my case I would get sqrt(lambda) = my_ms for dirichlet where my_ms is the zeroes for the bessel function. In this case it will be
sqrt(lambda)= 2.405 ; 3.382; 5.136; 5.520 ...
and for neumann
sqrt(lambda) = 0; 1.841: 3.054; 3.832...
can anyone check if these values are right so I...
Ok guys, thanks for all the help. Here's what I got. How do you guys get the tex code, do ypu write it by hand or do you have any help software?
I didnt do it exactly as you wrote J77, but it's the same way of thinking.
\frac{1}{\Theta}\frac{\partial^2\Theta}{\partial\theta^2}=const.=-k...
rR'/R + r^2R''/R + theta''/theta + r^2*lambda = 0
but I still don't see how to continue. I would really appreciate if you would show some steps on how to solve this, since I'm kind of lost. In the other assignmensts I've solved it've only been like X''/X = Y'/Y. But here it looks much more...
Yeah, well that's what I did. But I wrote it as u(r,Theta) = R(r)*Theta(theta). And that's how I got R'/R + rR''/R + theta''/(r*theta) + lambda = 0
I just applied the laplace on it and divided everything with R*Theta
no, I'm sorry, I cant. Dont know how tex works.
I know that the next thing is to separate the variables, but I don't get it right, that is as far as I get.
solve the Helmholtzequation laplace(u) + lamda*u = 0 in the unit circle with neumann condition for r = 1
I don't get very far on this problem. What I start with is rewriting the problem with how laplace looks in this case.
laplace(u) = (1/r) d/dr(r * du/dr) + (1/r^2) * d^2u/dtheta^2)
so...
I have a square area with the length a. The temperature surrounding the square is T_0 except at the top where it's T_0(1+sin(pi*x/a)). They ask for the stationary temperature in the area. In other words, how can the temperature u(x,y) inside the area be written when the time = infinity.
The...
