MEMORANDUM *

Omar Mendez-Contreras appeals his sentence for possession of cocaine with intent to distribute in violation of 21 U.S.C. § 841 (a)(1). Mendez-Contreras claims that the conduct of the police and one of its cooperating sources during the investigation constituted sentencing entrapment *483 and that the district court clearly erred in deciding that no sentencing entrapment had occurred. He contends the court erred in failing to make a downward departure in his sentence based on his post-sentence rehabilitation.

Mendez-Contreras’ argument that he suffered sentencing entrapment is unavailing. Sentencing entrapment occurs when a defendant is unduly pressured by the government to commit a crime of greater severity than the defendant was originally willing to commit. U.S. v. Robinson, 94 F.3d 1325 , 1328-29 (9th Cir. 1996). This court accepts the district court’s factual conclusion of whether sentencing entrapment occurred unless the conclusion is clearly erroneous. See, e.g., U.S. v. Sanchez-Lopez, 879 F.2d 541 , 557 (9th Cir.1989). Mendez-Contreras has the burden of proving such entrapment, by a preponderance of. the evidence. U.S. v. Riewe, 165 F.3d 727, 729 (9th Cir.1998).

Although Mendez-Contreras initially expressed surprise that Haines, the source cooperating with the police, wanted to purchase a half-kilo of cocaine, he expressed no unwillingness to produce that amount of cocaine. On the contrary— Mendez-Contreras’ only apparent reluctance was in ensuring that he would receive payment. Once the terms of the deal were resolved and Haines called to request actual delivery, Mendez-Contreras again expressed no reluctance and delivered the cocaine in less than four hours. During the course of Mendez-Contreras’ smaller transactions with Haines, Mendez-Contreras had commented about a half-kilo transaction he had undertaken with someone else, whom Mendez-Contreras feared would inform on him. The evidence supports the district court’s decision to reject the entrapment argument. The court did not err when it found that Mendez-Contreras showed no'reluctance to produce the half-kilo. The court’s finding showed it considered Mendez-Contreras’ arguments and rejected them. See U.S. v. Parrilla, 114 F.3d 124, 128 (9th Cir.1997).

Neither can Mendez-Contreras prevail on his contention that the district court erred when it failed to make a downward departure on account of his post-sentence rehabilitation. The district court considered Mendez-Contreras’ request, but expressed uncertainty about whether it had the legal authority to undertake a downward departure below the minimum sentence established by a statute. The district court concluded that even if it had this authority, it would not use its discretion to make such a departure. The court reached this conclusion after noting that Mendez-Contreras had been involved in two infractions during his imprisonment thus far. Such discretionary decisions not to undertake a downward departure for post-sentence rehabilitation are, like other discretionary decisions not to make a downward departure, unreviewable by this court. U.S. v. Hock, 172 F.3d 676, 681-82 (9th Cir.)(where the district court recognizes that it has authority to make a discretionary downward departure for post-conviction rehabilitation but chooses not to exercise that discretion, the court lacks authority to review that decision), cert. denied 528 U.S. 913 , 120 S.Ct. 265 , 145 L.Ed.2d 222 (1999).
