WebSep 26, 2024 · The variation of the partial cross-section σ l with the incident energy has the form of a classical resonance curve. The quantity Γ is the width of the resonance (in energy). We can interpret the Breit-Wigner formula as describing the absorption of an incident particle to form a metastable state, of energy E 0, and lifetime τ = ℏ / Γ.
The relativistic Breit–Wigner distribution (after the 1936 nuclear resonance formula of Gregory Breit and Eugene Wigner) is a continuous probability distribution with the following probability density function, $${\displaystyle f(E)={\frac {k}{\left(E^{2}-M^{2}\right)^{2}+M^{2}\Gamma ^{2}}}~,}$$where … See more The probability of producing the resonance at a given energy E is proportional to f (E), so that a plot of the production rate of the unstable particle as a function of energy traces out the shape of the relativistic Breit–Wigner … See more In experiment, the incident beam that produces resonance always has some spread of energy around a central value.
