The entangled states of three-level of trapped ion and two phonons (into coherent state) in Λ configuration forming a Hilbert space of 12-dimensional (D) are analyzed. The concurrence is considered "such as a quantum measure" in trapped ion-coherent state system. Four values of Lamb-Dicke parameter (LDP), = 0.005, 0.07, 0.08 and 0.09 are investigated by the worths of concurrence. We demonstrate that as is increased, sudden birth of entangled states in the system is increased. Thus, establishing of entangled states can be tuned by LDP.
