Abstract

Traditional nonrelativistic impulse-approximation treatments of $p$ -nucleus scattering using a local nucleon-nucleon $t$ matrix neglect nuclear currents which are intrinsic to relativistic approaches also employing a local $t$ matrix. Inclusion of these current terms is essential to the understanding of the spin-difference function, $(D_{qk} + D_{kq}) + i (P - A y)$ , as shown by comparison with ${}^{12}C (p, p^{'}) {}^{12}C^{*} (12.71 MeV, 1^{+}, T = 0)$ spin-difference data at 150 MeV.
