%X We present an experimental study on electromagnetically induced absorption (EIA) in the closed transition of a degenerate two-level Cs atomic system.The coupling and probe lasers coupled with the transition 6S1/2 F=4 to 6P3/2F'=5 of caesium atom. The signal of EIA was obtained and the frequency detuning and intensity effect of the pumping laser were experimentally investigated. The EIA signal in 6S1/2 F =4 to 6P3/2F'=4 and 6S1/2 F =4 to 6P3/2F'=3 open transitions was also obtained. As the repumping laser couples with the transition of 6S1/2 F =3 to 6P3/2F'=4, the EIA signal is increased due to the hyperfine optical pumping.
