The spectral index γ of the particle flux, J∝E-γ, at energies between 4×1018 eV and 4×1019 eV is 2.69±0.02(stat)±0.06(syst), steepening to 4.2±0.4(stat)±0.06(syst) at higher energies. The hypothesis of a single power law is rejected with a significance greater than 6 standard deviations. The data are consistent with the prediction by Greisen and by Zatsepin and Kuz’min.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2013-11-27T14:47:07Z No. of bitstreams: 1 10.1103PhysRevLett.101.061101.pdf: 269381 bytes, checksum: 65d980bcc3fbb70829cd1a3cff8badbe (MD5)Approved for entry into archive by Alda Lima da Silva (sivalda@ufba.br) on 2013-11-29T19:12:52Z (GMT) No. of bitstreams: 1 10.1103PhysRevLett.101.061101.pdf: 269381 bytes, checksum: 65d980bcc3fbb70829cd1a3cff8badbe (MD5)Made available in DSpace on 2013-11-29T19:12:52Z (GMT).
