The hyperon puzzle, the observation that the two-solar-mass neutron stars existence is hardly explained by all models predicting the appearance of hyperons in the neutron star core is currently one of the unsolved key issues in the physics of compact stars. An experimental study of the reaction (e,e′K) on 40Ca 48Ca nuclei to study the isospin dependence of hyperon dynamics has been proposed, by the Jefferson lab hypernuclear collaboration, and approved by the Jefferson Lab (JLab) PAC. This paper describes a proposal to make a complementary study by extending it to 208Pb, whose properties largely reflects those of the uniform nuclear matter present in the interior of the neutron stars making it the ideal one for this task.
