Comment on “Theoretical study of the pressure effect on the electron-capture β decay of ${}^7\mathrm{Be}$ in ${}^7\mathrm{BeO}$ and ${}^7\mathrm{Be}$${\mathrm{(OH)}}_2”$

We comment on a recently published paper that has demonstrated that the increase in the electron-capture nuclear decay rate of ${}^7\mathrm{Be}$ in ${}^7\mathrm{BeO}$ under compression can be accounted for by the phase transformation of BeO from the wurtzite to the rock-salt structure.
