The magnitude of the 15N(n,γ)16N reaction rate in asymptotic giant branch stars depends directly on the neutron spectroscopic factors of low-lying 16N levels. A new study of the 15N(d,p)16N reaction is reported populating the ground and first three excited states in 16N. The preliminary spectroscopic factors are near unity as expected from shell model calculations, resolving a longstanding discrepancy with previous experiments. The data and analysis are presented. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlikeLicence.
