Npt. Bateman et al., THICK TARGET YIELD OF AL-26 FROM THE C-12(O-16,X)AL-26(GS) REACTION, Physical review. C. Nuclear physics, 57(4), 1998, pp. 2022-2030
Clayton and Jin have proposed that Al-26 in the early solar system was
made by oxygen-rich cosmic rays through the C-12(O-16,x)Al-26(g.s). r
eaction. To test their proposal we have measured the yield of Al-26(g.
s). from this reaction using the activation method. We find that the y
ield is too low to explain the Al-26/Al-27 ratio that has been observe
d in carbonaceous chondrite meteorites.
