Abstract：
n-and 2n-transfer reaction products ¹⁰Be and ¹¹Be at large c.m. angles were measued in a specially designed set-up for the bombardment of ⁹Be by ⁶He at 150MeV. In total 371 ¹⁰Be and 5 ¹¹Be events, corresponding to 1n-and 2n-transfer respectively were identified. The experimental differential cross-sections obtained are 0.11±0.02mb/sr(θ _cm≈137.4°) and 1.0±0.7μb/sr(θ _cm≈133.4°) for 1n- and 2n-transfer, respectively. Such results indicate that the differential cross-section of 1n-transfer is about 100 times higher than that of 2n-transfer at large c.m. angle in the reaction studied. Calculation using zero range Distorted Wave Born Approximation(DWBA) for 6He under ⁵He-n and α-2n two-cluster models are performed and discussed.
