The cross sections and analyzing powers for knockout from the 1{ital d}{sub 3/2}, 1{ital d}{sub 5/2}, and 2{ital s}{sub 1/2} states of {sup 40}Ca in the {sup 40}Ca({ital p},2{ital p}){sup 39}K reactions at {ital E}=200 and 300 MeV are analyzed with both zero-range and finite-range relativistic distorted-wave impulse approximation (DWIA) calculations. We employ the relativistic Love-Franey model for nucleon-nucleon {ital t} matrix and the global Dirac optical potentials by Hama {ital et} {ital al}. The finite-range calculations are performed by using the Monte Carlo method. The calculated analyzing powers at 300 MeV are in good agreement with the data except the 1{ital d}{sub 5/2} state. The analyzing power in the finite-range calculation is more sensitive to the rms radius of the bound state wave function compared with the zero-range calculation. The extracted spectroscopic factors for {ital d} states in the finite-range calculation are closer to the values obtained by other reactions. The Monte Carlo method is effective to calculate the transition matrix elements included in the high partial waves of the distorted wave functions.
