  We present microscopic cluster model calculations for the 1p and 2p decays of
the 0+2 and 2+2 states of 10C. With the R-matrix method, we have estimated the
decay widths. The obtained 1p and 2p decay widths are in good agreement with
the recent experimental data and support the validity of the di-proton
approximation for the 2p decay of 10C(0+2). We also show the suppression of the
1p decay of the 10C(0+2) state due to the structure mismatch with the decay
channel.
