C003700100013 ANALYSIS The n-alpha phase shifts of Stammbach and Walters C003700100014 were used with the program MOCCASINS to calculate the C003700100015 effective analyzing power below E(n) = 17.6 MeV. C003700100016 At 17.6 and 20.9, the smoothed set of Niiler phase C003700100017 shifts were employed. C003700100018 Between 20.9 and 21.9 MeV, the energy dependence of theC003700100019 analyzing power was assumed linear and was obtained C003700100020 from Mutchler and Niiler.
