New experimental limit on the electron stability and non-paulian transitions in Iodine atoms

A new limit on the mean life of the electron in the “disappearance” approach has been established: τ e >4.2(2.4)·10 24 yr at 68% (90%) C.L., by using the ≃100 kg DAMA NaI(Tl) set-up at the Gran Sasso National Laboratory of INFN.
