Suppression of the centrifugal barrier effects in the off-energy-shell neutron + ¹⁷O interaction

NUCLEAR REACTIONS ²H(¹⁷O, α¹⁴C), E=41, 43.5 MeV; measured α and ¹⁴C particle spectra, (¹⁴C)α-coin, angular distributions, yields using position-sensitive silicon detectors (PSD) at LNS, Catania, and at NSL, Notre Dame. CD₂ target; deduced momentum distributions, Q value. DWBA analysis. ¹⁷O(n, α)¹⁴C, E(cm)=0-350 keV; deduced yields, angular distributions, neutron from quasifree breakup of deuteron. ¹⁸O; deduced resonances, J, π, and excitation functions. Trojan Horse method (THM), and suppression of centrifugal barrier. Comparison with previous studies. Relevance to neutron-induced reactions in nuclear reactors, and nucleosynthesis in astrophysics.
