摘要
The 1809-keV gamma ray from the decay of Al-26(g) is an important target for gamma-ray astronomy. In the convective C/Ne burning shell of massive presupernova stars, the Na-23(alpha,p)Mg-26 reaction directly influences the production of Al-26. We have performed a direct measurement of the Na-23(alpha,p)Mg-26 reaction cross section at the appropriate astrophysically important energies. The stellar rate calculated in the present work is larger than the recommended rate by nearly a factor of 40 and could strongly affect the production of Al-26 in massive stars.
