First Measurement of the EMC Effect in $^{10}$B and $^{11}$B

Nuclear Experiment 2023-08-01 v3

Abstract

The nuclear dependence of the inclusive inelastic electron scattering cross section (the EMC effect) has been measured for the first time in 10^{10}B and 11^{11}B. Previous measurements of the EMC effect in A12A \leq 12 nuclei showed an unexpected nuclear dependence; 10^{10}B and 11^{11}B were measured to explore the EMC effect in this region in more detail. Results are presented for 9^9Be, 10^{10}B, 11^{11}B, and 12^{12}C at an incident beam energy of 10.6~GeV. The EMC effect in the boron isotopes was found to be similar to that for 9^9Be and 12^{12}C, yielding almost no nuclear dependence in the EMC effect in the range A=412A=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.
