The transitions 1s2s3S-1s2p3P of Si12+ have been excited using the beam-foil method, and the wavelengths measured for the first time, for beam energies in the range 21-57 MeV. The measurements may be used to test calculations of the 3P fine-structure splitting to +or-1%, and when better calculations become available, the Lamb shift contributions to the transitions energy may be evaluated to +or-11%.
