Deuteron beam impinge at the Thorium-232

Dear expert,
I recently simulated deuteron beam impinge at the Thorium-232, in which the following nuclear reaction occurs: 90-TH-232(D,4N)91-PA-230.
Then I calculated the yield of Protactinium-230 in the Thorium target. However, the results given by FLUKA are half of those given by experimental data and PHITS.https://doi.org/10.1016/j.apradiso.2021.109676. I don’t know what went wrong and hope the experts can help me. Attached below is my input file.
Thank you very much.
