The Hamiltonian of the helium atom, under the assumption that the mass of the nucleus is much greater than that of the electrons and ignoring the spin, is of the form: Where are the position and momentum of the electron and is the atomic number of helium. Note that the first four terms are simply the sum of two Hamiltonians corresponding to a hydrogen atom for each electron; while the last term represents the interaction between both electrons. i) Investigate...

Answer d
a. (4 points) Write the Hamiltonian for the neutral Li atom, explicitly including each kinetic and potential energy term. b. (4 points) For a one-electron atom, the 2s and 2p orbitals are degenerate. Why does one electron in Li occupy the 2s orbital instead of 2p? How does that relate to the expectation values for the radii of 2s and 2p you computed earlier on this homework? c. (4 points) Li has an ionization energy of 5.39 eV....

Suppose there are two identical gas cylinders. One contains the monatomic gas helium (He), and the other contains an equal mass of the monatomic gas radon (Rn). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEHe/KERn of the average kinetic energy of an atom of helium to the average kinetic energy of an atom of radon.

Suppose there are two identical gas cylinders. One contains the monatomic gas helium (He), and the other contains an equal mass of the monatomic gas argon (Ar). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KE(He)/KE(Ar) of the average kinetic energy of an atom of helium to the average kinetic energy of an atom of argon.

An atom of beryllium (m = 8.00 u) splits into two atoms of helium (m = 4.00 u) with the release of 92.2 keV of energy. Suppose the beryllium atom moved in the positive x direction and had a kinetic energy of 44.0 keV. One of the helium atoms is found to be moving in the positive x direction. Find the direction of motion of the second helium, and find the velocity of each of the two helium atoms. Solve...
