Helium Atom
... The emission spectra of He consists of a number of series in the visible region of the spectrum as well as in the near & far UV regions. There are twice as many line series as for the alkalis; two principal series in the visible and near UV, as well as two diffuse, two sharp and two fundamental seri ...

Finite Nuclear Size Effect - Physics
... nucleus will instead be described with a finite size and a uniform distribution of charge. This will produce an energy potential that will require a different approach. After producing the potential from the assumption of a uniformly distributed charge over a finite sized nucleus, the Hamiltonian is ...

... atom. (This formula foreshadows the fact that, in general, the ground state of any system is the most in need of a quantum description.) c. Taking λ/r ≤ 0.1 as the (arbitrary) cut-off when classical mechanics begins to be valid as Bohr’s quantum number n increases, calculate the lowest (smallest n) ...

Series 5 - Problems
... As a simple (but instructive) example of time evolution, let’s consider the first physical scenario we learned for time-independent quantum mechanics - the particle in a box. Take V (x) = 0 for 0 < x < L and V (x) = ∞ everwhere else. a) What are the energy eigenstates, the energy eigenvalues (in ter ...
