Yes. In fact, if a Roman Catholic is unable to partake of the Eucharist in a Roman Catholic church, they may do so in an Orthodox one. The RCC considers Orthodox sacraments valid (including their ordinations to the priesthood).

The answers is no, if he wasn't divorced,yes,because the catholic church recognises the orthodox church as valid since they were one church before.However if he is divorced he is not allowed in either catholic or orthodox. A Catholic can marry any non- Catholic, and it is recognized as a sacrament in the Catholic church. Only when the individual has been previously married there is an issue. In which case that individual must have their previous marriage annuled. The Catholic church permits Catholics to marry in the Orthodox church and it is a sacrament. I have spoken to Catholic priests and Catholic Bishops and they do not see a problem with a Greek annulment, as being an impediment. If that individual did not have their marriage previously annulled than it would be an issue.
as far as i know they share everything with the roman catholic church except priests can marry and the pope is not the head of there church
