The atomic sample, having a peak density $\\sim 5\\cdot10^{13}$ atoms/cm$^{3}$, temperature $\\sim$ 65 $\\mu$K and initially prepared in the F = 1 lower energy $^{87}$Rb hyperfine component, is optically pumped to the higher energy F = 2 hyperfine level. Measurements are made of the transient hyperfine pumping process and of the time evolution of scattering of near resonance probe radiation on the $F = 2 \\rightarrow F' = 3$ transition.
