  1. It is shown that the results calculated using the ccdwa are agreement with one of the accurate quantum mechanics employing the same potential. quantum mechanical tunneling is important in near threshold, and classical trajectory calculation is not good for prediction of the cross sections. the reaction cross sections calculated using different potentials is different, which show that the investigation of reaction cross section can provide evidence for test of accuracy of the potential energy surface

    研究發現:勢能面相同時用ccdwa方法計算的截面和公認精確的量子力學結果比較符合;閾能附近的量子力學隧道效應較為顯著,準經典彈道方法不能很好的預言其截面;用不同勢能面計算的反應截面有差別,說明反應截面的研究能為檢驗勢能面的準確性提供依據。
