The Attenuate Function in LCAC-SW Method

The style of the attenuate function f(R) in LCAC-SW (Linear Combination Arrangement Channel-Scattering Wavefunctions) method is discussed.From the calculations,it can be seen that f(R) should attenuate to zero at classical return point in a way sharper than 1-exp (-βR), such as f(R) =1-exp (-αR⁶).Meanwile,it is proposed that the closed channel functions be distributed in the region (0～R_W) at which quasi-classical approximation isn't applicable.
