Relativistic time dilatation and the spectrum of electrons emitted by 33 TeV lead ions penetrating thin foils

B. Najjari, A. Surzhykov, A. B. Voitkiv

We study the energy distribution of ultrarelativistic electrons produced when a beam of 33 TeV Pb${}^{81+}$(1s) ions penetrates a thin Al foil. We show that, because of a prominent r…
