英文摘要	We study the molecular state in three-component Fermi gases with a single impurity of (6) Li immersing in a no-interacting Fermi sea of (4)0 K in the presence of an equal weight combination of Rashba-type and Dresselhaus-type spin-orbit coupling. In the region where the Fermi sea has two disjointed Fermi surfaces, we find that there are two Fulde-Ferrell-like molecular states with dominating contributions from the lower helicity branch. Decreasing the scattering length or the spin-orbit coupled Fermi energy, we find the Fulde-Ferrell-like molecular state with small center-of-mass momentum is always energy favored and the other one will suddenly disappear.; National Basic Research Program of China (973 Program) [2013CBA01502, 2013CB834100]; National Natural Science Foundation of China [11374040, 11475027, 11575027, 11274051, 11075020]; SCI(E); ARTICLE; 2; 255-258; 68
