Uncertainty Principle Using ΔEΔt ≥ ħ: an Unstable Particle Produced

question 37

Short Answer

Uncertainty principle using ΔEΔt ≥ ħ: An unstable particle produced in a high-energy collision is measured to have an energy of 483 MeV and an uncertainty in energy of 84 keV. Use the Heisenberg uncertainty principle to estimate the lifetime of this particle. (ħ = 1.055 × 10^-34 J ∙ s = 6.59 × 10^-16 eV ∙ s)
