摘要：

We improved the accuracy of calculating the exchange alpha-nucleus real potential by suggesting a simple expression for the nondiagonal density matrix of alpha-particle {rho(alpha)((r) over right arrow<(r)over right arrow'>)}. We found that this expression reduces the error in calculating the total alpha-nucleus potential by more than 20% compared with using the density matrix expansion method to treat rho(alpha)((r) over right arrow<(r)over right arrow'>). [S0556-2813(99)04903-1].
