摘要

在這項工作中，我們使用BSCR方法詳細的計算Be之共振態的能量和寬度。首先先固定θ值，然後將β值由0.10每間格為0.01改變到0.99，找出可用的θ值。再針對這個θ值找出穩定的可使用的β值區間，同時並定出我們的最佳β值。最後我們發現這個計算值和其他理論計算值和實驗值相當一致。

In this work, we use BSCR method to calculate the resonances energy and width of the Be atom. We first fixed the θ value, and then the β value will be changed with a step of 0.01 in the region of 0.10-0.99. From this procedure we can calculate out the available θ value and the optimized β value corresponding to this θ value. Finally we find our present results are quite in good agreement with earlier experimental data and other theoretical results.
