pwba()

void pwba	(	int	Ni,
		int	Li,
		double	ki,
		int	Nf,
		int	Lf,
		double	kf,
		int	L,
		cArrays &	Tdir,

		bool	exchange = true
	)

This function computes all contributions to the T-matrix for the specified total angular momentum L in the Born approximation of the first-order. The contributions depend on all such "li" and "lf" that the following conditions must be satisfied: |li - Li| <= L <= li + Li |lf - Lf| <= L <= lf + Lf This results in the following bounds on "li" and "lf": |Li - L| <= li <= Li + L |Lf - L| <= lf <= Lf + L

Parameters

Ni	Initial atomic state.
Li	Initial atomic state.
Nf	Final atomic state.
Lf	Final atomic state.
ki	Initial projectile momentum.
kf	Final projectile momentum.
L	Total angular momentum.
Tdir	List of direct scattering T-matrices for all allowed "lf".
Texc	List of exchange scattering T-matrices for all allowed "lf".
direct	Whether to compute direct scattering contributions.
exchange	Whether to compute exhange scattering contributions.
