Internal motions in three-body bosonic Thomson atoms
Y. Z. He, Bao Cheng-guang
A three-body bosonic Thomson atom, namely a system of three charged bosons in a harmonic trap, with a very large Wigner parameter, has been studied. The states with zero angular momentum and even parity denoted as 0 n + have been calculated and analysed; the basic modes of excitation of this system have been revealed. It was found that each lower 0 n + state ( n is from 1 to 5) has its own means of internal motion. Although the size of the system is very sensitive to the strength of the trap, the other features are found to be insensitive to the strength if the system remains in the Wigner regime. The breathing mode was found to be the easiest to excite.
