The radioisotope 26 Al is an important probe of the interstellar medium of our galaxy, but its production is now still not well determined partially due to the lack of knowledge of the important states in 26Si, which dominate the large uncertainty in the 25Al(p,γ)26Si reaction rate at nova temperatures. We give an update on two experiments that were performed to study these states. One is a measurement of the 27Si(p,d)26Si * reaction at the NSCL, and the other one is a measurement of the 25 Al+p elastic scattering with the CRIB facility at RIKEN. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlikeLicence.

Abstract

The radioisotope 26 Al is an important probe of the interstellar medium of our galaxy, but its production is now still not well determined partially due to the lack of knowledge of the important states in 26Si, which dominate the large uncertainty in the 25Al(p,γ)26Si reaction rate at nova temperatures. We give an update on two experiments that were performed to study these states. One is a measurement of the 27Si(p,d)26Si * reaction at the NSCL, and the other one is a measurement of the 25 Al+p elastic scattering with the CRIB facility at RIKEN. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlikeLicence.
