    "abstract": "We propose a scheme for creating atomic coherent superpositions via\nstimulated Raman adiabatic passage in a Lambda-type system where the final\nstate has twofold levels. In the employ of a control field, the presence of\ndouble dark states leads to two arbitrary coherent superposition states with\nequal amplitude but inverse relative phase without the condition of\nmulti-photon resonance. In particular, two orthogonal maximal coherent\nsuperposition states are created when the control field is resonant with the\ntransition of the twofold levels. This scheme can also be extended to manifold\nLambda-type systems.",
