Unformatted text preview: ground state is suddenly placed in a static electric field E z at t=0. You may assume the dipole operator μ to be 1/2 qZ 2 /a, where a is some length. a) (20 pts) What would you expect the energy and the state vector to be as a function of time for t>0? Perform no integrations but determine the quantities that would go into the integrals. b) (20 pts) Compute the actual probability that the system will remain in its ground state. ( z ) = { 1 / 2 } 1 / 2 exp(2 z 2 / 2); 2 = m / h 4. (40 pts) a) (20 pts) Write out the electron configurations, term symbols, and wavefunctions with specific values of L and S for the 5 lowest states of the He atom. Order these states in terms of increasing energy. b) (20 pts) Assuming electrons to be S=1 bosons, redo part a)....
