Parities of levels in Mg/sup 24/ and Si/sup 28/ were found from observations on alpha-particle groups emitted in the forward direction following bombardment of O/sup 16/ by C/sup 12/ and O/sup 16/ ions. The interpretation depends only on conservation laws and not on any assumption about the reaction mechanism. Of the lowest seven known states of Mg/sup 24/ (E/sub ex/ = 0, 1.37, 4.12, (E/sub ex, = 0, 1.77, 4.62, 4.98, (6.28) Mev! only the two in parentheses have parity (-)/sup J+1/. The spins (J) of all these levels are known, and because these two are the only members with J odd, it follows that all 12 levels have positive parity. (auth)
