Sažetak
We report precision determinations of the beam normal single spin asymmetries (A_nA n ) in the elastic scattering of 0.95 and 2.18~GeV electrons off ^{;12}; 12 C, ^{;40}; 40 Ca, ^{;48}; 48 Ca and ^{;208}; 208 Pb at forward angles. The first measurements of A_nA n for ^{;40}; 40 Ca and ^{;48}; 48 Ca are found to be similar to that of ^{;12}; 12 C, consistent with expectations. We also report A_nA n for ^{;208}; 208 Pb at two new momentum transfers (Q^2 2 ) extending the previous measurement. Our new data confirm the surprising result previously reported, with all three data points showing significant disagreement with the results from the Z\leq 20Z≤20 nuclei. These data confirm our basic understanding of the underlying dynamics that govern A_nA n for nuclei containing \lesssim 50≲50 nucleons, but point to the need for further investigation to understand the unusual A_nA n behaviour discovered for scattering off ^{;208}; 208 Pb.
