Abstract : The R-matrix method is used to calculate photoionisation from the first excited state 3s3p2 3pe of Si+. The lowest two triplet terms 3s3p 3po and 3p2 3pe of the residual ion Si++ are included in the calculation. They are approximated by configuration interaction wavefunctions which are constructed from six spectroscopic orbitals : 1s, 2s, 2p, 3s, 3p, 3d. Partial and total cross-sections are tabulated for photon energies ranging from threshold 705 A up to 2.5 Ryd 365 A. Some of the 3p2np autoionising resonances are delineated and shown graphically.
