First Measurement of the EMC Effect in \(^{10}\)B and \(^{11}\)B

The nuclear dependence of the inclusive inelastic electron scattering cross section (the EMC effect) has been measured for the first time in \(^{10}\)B and \(^{11}\)B. Previous measurements of the EMC effect in \(A \leq 12\) nuclei showed an unexpected nuclear dependence; \(^{10}\)B and \(^{11}\)B w...

Zusammenfassung:The nuclear dependence of the inclusive inelastic electron scattering cross section (the EMC effect) has been measured for the first time in \(^{10}\)B and \(^{11}\)B. Previous measurements of the EMC effect in \(A \leq 12\) 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 \(^9\)Be, \(^{10}\)B, \(^{11}\)B, and \(^{12}\)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 \(^9\)Be and \(^{12}\)C, 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.
