Recently Lee has suggested that the reaction K- + d \rightleftarrows∑- + p might lend itself to a determination of the spins of the negative K meson and negative ∑ particle. Because of the mysterious degeneracy of the mass levels of heavy mesons, however, the application of the detailed balancing arguments is not so simple as was the case with the positive pion nuless heavy mesons with different names represent the competing modes of decay of a single kind of heavy mesons.
In this paper, we propose a possible experimental method to determine the spins of the negative K meson and negative ∑ particle from the observation of the process K- + d \rightleftarrows∑- + p by using a K meson beam which is in general a mixture of distinct kinds of K mesons.
