Figure 1
Fits of equation (3 ) to Lynn & Seeger (1990 ) resonant neutron scattering lengths for naturally abundant Gd with respect to energy; the real part (b0 + b′) is in blue and the imaginary part (b′′) is in red. Crosses mark values from Lynn & Seeger (1990 ) with the sign of b′′ reversed; curves are from the fitted coefficients. The respective residuals from the fits are shown as blue and red lines close to zero. |
