The hole-doped Cu-O chains in Pr123 and Pr124 were studied using ARPES. The ARPES data showed that the Cu-O single chain in Pr123 and the Cu-O double chain in Pr124 are approximately 1/4 filled. Evidence indicate that the charge ordering occurs in the Cu-O single chain and is suppressed in the Cu-O double chain.
