Addendum to "Measurement of 23Mg(p,γ)24Al resonance energies"
Using recent data we reduce the systematic uncertainty in our measurement [Phys. Rev. C 76, 065803 (2007)] of the excitation energy of the second level above the proton threshold in Al24 and find it to be 2523(3) keV, a factor of two improvement over our previously reported value of 2524(6) keV. © 2008 The American Physical Society.
