T. Yoshimura et al., ALPHA SPECTROSCOPIC FACTORS FOR LI-6, LI-7, BE-9, AND C-12 FROM THE ((P)OVER-RIGHT-ARROW,P-ALPHA) REACTION AT 296 MEV, Nuclear physics. A, 641(1), 1998, pp. 3-20
Three-body breakup cross sections and analyzing powers for the Li-6, L
i-7, Be-9 and C-12((p) over right arrow, p alpha) reactions were measu
red at an incident energy of 296 MeV. Data were analyzed using the pla
ne wave impulse approximation (PWIA) and the distorted wave impulse ap
proximation (DWIA) and compared with previous studies. DWIA calculatio
ns reproduce shapes of projected spectra and analyzing power distribut
ions fairly well with the exception of the C-12((p) over right arrow,
p alpha) Be-8 reactions. Extracted spectroscopic factors for Li-6, Be-
9 and C-12 are larger than those found in the previous studies. In con
trast, extracted spectroscopic factors for Li-7 agree with the previou
s work. This work suggests that the spectroscopic factor for Li-6 is s
imilar to 0.8, independent of incident energies and reaction types. (C
