摘要: The complex plane methodology for computing continuum-continuum matrix elements (CCME) can be useful in practical applications, even when a huge number of CCME are required converged calculation. This conclusion arises as consequence the substantial stability against θ elements' real and imaginary parts, YR YI, enabling one to economically evaluate CCME. For more refined values, criterion dYR(θ)/dθ = 0 (and separately dYI(θ)/dθ `irregular' integral, if necessary) may superior cusp-condition, since latter would imply that two quantities which should represent values conceptually independent integrals, were optimized they correlated.
