Unformatted text preview: remain in the ground state. Show that this is consistent with the transition rate (Bransden 9.61) for a twolevel system with harmonic perturbation. (Previously we focused on this equation when we were near the resonance of one of the two terms. Now you have to show that as 0, P (1) ab 0, using the relationship between A and A .) 5. (a) Find a solution that is stationary on average for motion of a nonrelativistic classical particle of charge q and mass m , under the motion of a periodic electrical eld E y sin( t ). You should nd simple harmonic motion of frequency in the y direction. (b) Now calculate the total energy radiated per period of this oscillation, using the Larmor formula for instant radiated power of a classical charged particle of acceleration a : in SI units, P = e 2  a  2 6 c 3 .
