Result
1.5 GeV (gigaelectronvolts)
Comparison as energy for 1.5 GeV
≈ ( 0.018 ≈ 1/56 ) × mass-energy equivalent of a W boson ( ≈ 1.3×10^-8 J )
≈ ( 0.029 ≈ 1/34 ) × initial per beam operating energy of the CERN Large Electron Positron Collider in 1983 ( ≈ 8×10^-9 J )
≈ 1.6 × mass-energy of a proton ( 1 m_p c^2 )
