C. Michotte et al., NEW LIMITS FOR THE NE-19(P,GAMMA)NA-20 ASTROPHYSICAL REACTION-RATE FROM DIRECT MEASUREMENTS USING RADIOACTIVE BEAMS, Physics letters. Section B, 381(4), 1996, pp. 402-406
Inexplosive stellar hydrogen burning, the hot CNO cycles and the rp-pr
ocess are mainly linked by the reaction sequence O-15(alpha,gamma) Ne-
19(p,gamma)Na-20. Using intense Ne-19 radioactive beams, both the Ne-1
9(p,gamma) and the Ne-19(d,n) reaction have been studied. Upper and lo
wer limits for the Ne-19(p,gamma) reaction rate have been deduced, all
owing to conclude that the O-15(alpha,gamma) reaction is most likely t
he bottleneck reaction.
