Abstract

We report a high-precision mass measurement of Si24, performed with the Low Energy Beam and Ion Trap (LEBIT) facility at the National Superconducting Cyclotron Laboratory. The atomic mass excess, 10753.8(37) keV, is a factor of 5 more precise than previous results. This substantially reduces the uncertainty of the Al23(p,γ)Si24 reaction rate, which is a key part of the rapid proton capture (rp) process powering type I x-ray bursts. The updated rate constrains the onset temperature of the (α,p) process at the Mg22 waiting point to a precision of 9%.
