How is energy transferred between atoms in a collision?
Consider two bare protons. One (A) is stationary (relative to some arbitrary massless observer); the other (B) is approaching A at 1 m/s. When they collide, I assume that they bounce.
What is the ...

Is the spin state of an atom related to the polarization of the photon it spontaneously emits?
From literature I've been reading, I find that scientists are able to "map" atomic states onto photon states. Are they talking about spin states and corresponding photon polarization states? Can ...

Why is there a factor of 1/2 in the interaction energy of an induced dipole with the field that induces it?
In this paper, there's the following sentence:
...and the factor 1/2 takes into account that the dipole moment is an induced, not a permanent one.
Without any further explanation. I looked ...

Do we have control on what an electron transition emits: light or heat?
I don't know quantum mechanical model. So, I'm referring to just bohr's model of atom.
Any atom emits energy when it makes transition from higher excited state to lower excited state. Now, some times ...

How does electron excitation relate to atomic orbitals?
Taking off from the Rutherford-Bohr model,
Figure 1. Rutherford-Bohr model.
when an electron absorbs energy (from light, heat, or otherwise) it jumps to a higher energy level, or shell. Then when ...
