Chapter 44: Q22P (page 1364)

A $220 MeV$ $\sum^{-}$ particle decays: $\sum^{-} \to π^{-} + n$ . Calculate the total kinetic energy of the decay products.

Short Answer

Expert verified

The total kinetic energy of the decay energy is. $338 Mev$

Step by step solution

Law of conservation of energy.

The law of conservation of energy is define as the energy can neither be created nor destroyed, only converted from one form of energy to another form.

Calculate the total kinetic energy of the decay energy

The given reaction is written as:

$\sum^{-} \to π^{-} + n$

Solve the total kinetic energy of the decay energy as follows:

$\begin{matrix} Q = {(B E)}_{p} ~ {(B E)}_{R} \\ = - Δ m c^{2} + Q_{i n i t i a l} \\ = (m_{Λ^{0}} - m_{p} - m_{π^{-}}) c^{2} + Q_{i n i t i a l} \end{matrix}$

Substitute the values from the standard data

$\begin{matrix} Q = (1197.3 - 139.6 - 939.6 + 220) Mev \\ = 338 Mev \end{matrix}$

Thus, the total kinetic energy of the decay energy is. $338 Mev$
