Why can free lithium atoms not take part in an Auger process?
Shouldn't it be possible for an incoming photon to excite one of the 1s electrons to a 2p state (or one of even higher energy) and then for the excited electron to drop back to 1s and kick out the 2s ...

Minimum atomic clearance permitting motion
Suppose you were to build the piston and cylinder in a car engine atom-by-atom. Let's just say carbon, since you can make a lot of different shapes due to it's high valence.
So assuming you make the ...

Is the translational information all that matters, or do we need to take into account internal states?
For anyone in this community that's familiar with quantum teleportation, I need desperate help. I am currently working on my senior thesis and my goal is to teleport a molecule.
Background:
So in ...

Does this photon emission problem even make sense?
I came across this question in an introductory physics course awhile back and I never got over it: "A hydrogen atom has an electron in the n=5 orbit, what is the maximum number of photons that might ...

why is the transition $3p^53d^2 \to 3p^63d^1$ (hydrogen atom) forbidden?
What I was thinking is that in 3d subshell (l=2) we have two electrons with $$m_l=-2$$ (spin up and down)
and if we move to 3p we will fill the last vacant position - that is $$m_l=1$$ with spin down ...

What methods exist for us to measure the position and momentum of atoms that make up molecules?
In reference to this paper, http://iopscience.iop.org/1355-5111/8/1/014, we are able to localize atoms using homodyne measurement. Would it be too naive to consider we can measure the position of ...

How the radio-freqency magnetic field helps to record fluorescence signal
Suppose a sample of atoms (say rubidium), which is exposed to constant magnetic field, is irradiated with circularly polarized light so that the electrons are excited from lower S level (F=3) to P ...

Where to find probability density plots for all elements?
Does anyone know where I can find something similar to this, but for all elements?
I would love to find something with the same image quality.
Also, is there any software that can produce images ...

Evaluating Transition probability between different states of Hydrogen atom
I am trying to evaluate the inner product $<2S_{\frac{1}{2}},F',F'_{3}|\delta^{3}(x)\sigma_{i}P_{i}|2P_{\frac{1}{2}},F,F_{3}>$ It's written in the form $<nl_{j},F,F_{3}|$ Where ...
