摘　　要：Through mean-field calculations,we demonstrate that,in a large Z nucleus binding multiple muons,these heavy leptons localize within a few dozen femtometers of the nucleus.The mutual Coulomb interactions between the muons and protons can lead to a substantial decrease in proton chemical potential,surpassing 1 MeV.These findings imply that,in principle,the proton-dripline can be expanded on the nuclear chart,suggesting the possible production of nuclei with Z around 120.
