• The low-lying energy levels and various transition rates of six N=50 isotones from ^<89>Y to^ <94>Ru are calculated in the configuration space including one and two proton excitations from the 1p_<3/2> core orbit in addition to the (Og_<9/2>, 1p_<1/2>)^n configuration. Some particular levels, e.g., the second 2^+ state in ^<99>Zr, the first 7/2^+ and the second 3/2^- states in ^<91>Nb and almost all low-lying state in ^<91>Y, etc., are well explained by the present model. The effect of this extension of the configuration space is reflected more strongly on the transition rates. Especially, by taking account of the core excitation from the 1p_<3/2> orbit, the rates of the estimated. The E0, E2, E4, M4 and E5 transition rates in these nuclei are also calculated and compared with the experimental date. In some particular transitions in the heavier nuclei, the drastic discrepancies are obtained between the calculated results with and without the 1p_<3/2> core excitations.
