An Unstable Particle Produced in a High-Energy Collision Is Measured $483 \mathrm { MeV }$

question 18

Short Answer

An unstable particle produced in a high-energy collision is measured to have an energy of $483 \mathrm { MeV }$ and an uncertainty in energy of $29 \mathrm { keV }$ . Use the Heisenberg uncertainty principle to estimate the lifetime of this particle. $\left( h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } , 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \right)$
