Problem

A gamma-decaying level has a measured half-life

T_{1/2} = 15.0\,\mathrm{ns}

and an internal conversion coefficient

\alpha_{\rm IC} = 3.5

. Calculate the photon partial decay rate

\lambda_\gamma

and the photon partial half-life this transition would have if internal conversion were switched off.
