@@ -5,14 +5,14 @@ The 2015 summer run focused on the detection of neutral particles: low energy
X-ray, gamma ray and neutron emission after the muon is captured by the
nucleus.
The X-rays and gamma rays of interest are:
\begin{itemize}
\item muonic $2p-1s$ transition in aluminum: \SI{346.8}{\kilo\eV}
\item \SI{843.7}{\kilo\eV} gamma from the $\beta^-$ decay of \ce{^{27}Mg}

\item \SI{1808.7}{\kilo\eV} gamma from the first excited state of
\ce{^{26}Mg}
