Hi, i have problems understanding the Brilluoin zone to the bcc lattice
First, i wonder what the distances are, from the origo to the brillouin zone plane borders.
I firts thought it would be half the distance of the basis vectors (mine are 2pi/a, where a is my lattice constant, BUT its only...
I want to define (and find the sound velocity i iron).
can i read it through the dispersion curves of iron?
I am trying to see it through the group propagation velocity, vg = dw/dk, i. e the slope
of the dispersion relation w(k).
am i on the right track?
thanks
Ok, but for solid crystalic Iron, the major heat distributor is conduction, through vibrating the atoms and excitiing the oscillators into higher energy modes, and transferring the energy to the neighbours. is this a fair statement? What is the other (less contributing factors).uantum...
ok, thanks a lot. So that electromagnetism is exerting force - as photons - to excite the other atom into a higher energy lvl of that quantum oscillator?(in the quantum model)?
Hello. I am about to show how heat is transferred through crystals i. e metals
I know that it should be about conduction, and that the single quantum oscillators start vibrating in higher modes, due to the extra energy.
Now is the question: HOW exactly is the energy trasnferred...
anyone know how to read a Nilsson-diagram? I have a Np, z=93 atom and trying to see the proton diagram. How to see the deformation?
I start with the 82 lvl in the diagram and count upwards., 2 protons per lvl. But wouldn't it be the same amount of lines up to the ground state 5/2+ lvl of...
Calculate the square of the total spin operator and find all its eigenvalues. Use
the fact that in general the eigenvalues of the square of the angular momentum
operator is J(J + 1)¯h
2
to find the spin of the electron.
the firts one i have fixed..
Yes, i was sloppy. I meant that. But, I am asked to show the spin of the electron, by knowing that the eigenvalue of J2 is usually J(J+1)hbar...what do they mean?
sthg like solving for S in J^2 = L^2 + S^2 +2 L.S?
I should Use
the fact that in general the eigenvalues of the square of the angular momentum
operator is J(J + 1)h and show the spin of the electron.
I have J= L+S and J2 = L2+ S2
Homework Statement
But how could i find the spin of the electron
Yes, i thought so to in the beginning, and it is propably true...in that case, i should find out the recoil energy and speed of the nucleus whit mass M and atomic number Z
I start with: the recoil energy = -13.6 Z^2( which is the ground state energy) = Mv^2/2
a proton goes to a neutron, at the same time as a neutrino is flewn out..but should i only consider the neutrino energy and equal that to the recoil energy?
Hi
I have an atom with nuclear charge Z, mass M and no electrons (a bare nucleus) which captures an electron into its ground state. I am asked to calculate the kinetic energy and the recoil
speed of the nucleus after the electron capture...
I have the Z^2 (-13,6 eV) as usual, as the...
