Perhaps the word is 'product'? I am thinking along the lines that the cartesian product of the set of all Individuals and the set of all Events is the set of all possible Occurrences. Unfortunately, 'intersection' is quite a good word if we are thinking in natural language, and 'product' is not - not unless you are already thinking in terms of a mathematical vocabulary.
