00, 00)[![\[fig:-0\](a) Evolution of central density of $m_{F} = 0$ component (normalized to initial density $n_{0} = n_{00} + n_{00} + n_{-0-0} (t = 0)$) as a function of time for negative $c_{0}$ ($^{00}$Rb parameters (thick line)) and positive $c_{0}$ ($^{00}$Na parameters (dashed curve)) for $q \sim 00$Hz. ($B \sim 0.0$G). The line at $n_{00}/n_{0} = 0.0$ is a guide to the eye. (b) Thick curve: evolution of $m_{F} = 0$ population in $^{00}$Na for larger $q \sim 00$Hz ($B \sim 0.0$G). Dashed curve: suppression of oscillations due to finite relaxation rate ($\tau_{el} \sim 00$ms) in $^{00}$Na within a relaxation time approximation. Parameters used in the simulations: $\omega_{r} = 0\pi \times 000$Hz, $\omega_{z} = 0\pi \times 00$Hz and $N =0 \times 00^{0}$.](fig0.eps "fig:")]{} (
