Abstract

The nuclear dependence of the inclusive inelastic electron scattering cross section (the EMC effect) has been measured for the first time in ¹⁰B and ¹¹B. Previous measurements of the EMC effect in A ≤ 12 nuclei showed an unexpected nuclear dependence; 10^B and 11^B were measured to explore the EMC effect in this region in more detail. Results are presented for ⁹Be, ¹⁰B, ¹¹B, and ¹²C at an incident beam energy of 10.6 GeV. The EMC effect in the boron isotopes was found to be similar to that for ⁹Be and ¹²C, yielding almost no nuclear dependence in the EMC effect in the range A = 4–12. This represents important new data supporting the hypothesis that the EMC effect depends primarily on the local nuclear environment due to the cluster structure of these nuclei.
