Description

A study of the D0(1285) meson has been done in the 6-body channel anti pp → Kanti Kπω resulting from antiproton-proton annihilations. After some comments reinforcing the previously advanced value Isup(G) = O+, the paper gives an analysis of the selected channel. The work is carried out using (a) the calculated moments of the spherical harmonics and (b) a maximum likelihood method using Zemach's matrix elements. Both methods favour the assigment Isup(P) = 1+.
