Abstract:

A two-photon transition is used to convert an arbitrary fraction of the ⁸⁷Rb atoms in a |F = 1, m_f = −1〉 condensate to the |F = 2, m_f = 1〉 state. Transferring the entire population imposes a discontinuous change on the condensate's mean-field repulsion, which leaves a residual ringing in the condensate width. A calculation based on Gross-Pitaevskii theory agrees well with the observed behavior, and from the comparison we obtain the ratio of the intraspecies scattering lengths for the two states, a_|1,−1〉/a_|2,1〉 = 1.062(12).
