Abstract
Described is the new phenomenon of scalar S ∗−δ 0 meson mixing which is shown to be considerable and to be determined by the strong interaction coupling constants of the S ∗ and δ mesons with the K K channel and to be of the order of [(m K 0 − m K + )/m K 0 ] 1 2 , and not of ( m K 0 − m K + )/ m K 0 as would be expected from simple considerations. The reactions are discussed in which one can study this phenomenon.
