We investigate the effects of spontaneously generated coherence (SGC) on the electromagnetically induced transparency features in a four-level Λ-type system. We show that double-transparency windows and a controllable narrow absorption peak can be obtained with the presence of SGC. We present an equivalent system without the rigorous requirement of close-lying levels to observe the phenomena. We also experimentally demonstrate the corresponding features in a rubidium atomic beam.
