Peripheral elastic and inelastic scattering of ^{17, 18}O on light targets at 12 MeV/nucleon

NUCLEAR REACTIONS ¹³C(¹⁷O, ¹⁸O), E=12 MeV/nucleon; ¹²C(¹⁸O, ¹⁸O), (¹⁸O, ¹⁸O'), E=216 MeV; ¹³C(¹⁷O, ¹⁷O), (¹⁷O, ¹⁷O'), E=204 MeV; measured particle spectra, σ, σ(θ). ¹²C(¹⁶O, ¹⁶O), E=18 MeV/nucleon; analyzed previous σ(θ) data; deduced form factors, optical model parameters, WKB scattering amplitude, semiclassical absorption profile for WS potential, Argand diagram for S-matrix. Analysis by semimicroscopic double folding form factors, using six different approximations for the NN effective interactions. DWBA analysis of σ(θ) data. ^17,18O; deduced levels, J, π, deformation parameters. Relevance of ¹³C(¹⁷O, ¹⁸O) transfer reaction in deducing direct capture rates in ¹⁷F(p, γ)¹⁸Ne reaction of astrophysical importance, and influence on abundances of ¹⁵O, ¹⁷F, ¹⁸F and ¹⁸Ne.
