It is assumed that K* ofAlston et al.:Phys. Rev. Lett,6, 300 (1961); isI = 1/2, J = 1 (cf.C. H. Chan:Phys. Rev. Lett.,6, 383 (1961) and Beg and de Celles:Phys. Rev. Lett.,6, 428 (1961)). On the other hand, a scheme of resonances which includes (1 = 0, J =0+) will make the existence of a K’ (/ = $, J = 0+) needed to permit the construction of a strangeness-violating weak interaction axial current (cf. réf. (11)) highly desirable. Perhaps a K’ exists with mass value lower than K* (884 MeV).CrossRefGoogle Scholar
