Abstract: | Differential cross sections were measured for the reactions for angles ranging from θlab = 6° to 48°. Optical-model analysis was performed for elastic α-scattering from 9Be at Eα = 48, 65 and 104 MeV, and DWBA and CC calculations were done for the inelastic α-scattering at Eα = 65 MeV. DWBA calculations for the 9Be(α, 3He) reactions do not fit the transfer data so well and extracted spectroscopic factors are in disagreement with those of Cohen and Kurath and with values obtained from other reactions. Full CRC calculations assuming a band structure for the low-lying states of 10B and employing a modified set of Cohen and Kurath spectroscopic factors yield globally better fits both in shape and in absolute cross section for differential cross sections to low-lying states in 10B obtained in 9Be(α, t)10B at . In general, strong coupled-channel effects mainly affecting the distorted waves are observed both in entrance and exit channels. |
