Study of astrophysically important states in 26Si with the p(27Si,d)26Si* reaction and the p( 25Al,p)25Al elastic scattering

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.
