Electron capture decay rate ofV50

A \ensuremath{\gamma}-ray peak attributed to the deexcitation of the first excited state of $^{50}\mathrm{Ti}$ has been detected from vanadium metal by a large, low background intrinsic Ge detector operating in a salt mine. The partial half-life for the electron capture decay of $^{50}\mathrm{V}$ to the first excited state of $^{50}\mathrm{Ti}$ has been estimated to be ${1.2}_{\mathrm{\ensuremath{-}}0.4}^{+0.8}$\ifmmode\times\else\texttimes\fi{}${10}^{17}$ yr. A limit on the partial half-life for ${\ensuremath{\beta}}^{\mathrm{\ensuremath{-}}}$ decay is also obtained.
