SU(3) assignment and coupling of N*(1688)


A comparison of the two reactions γ + p → n + p and γ + p → π0 + p in the region of the third nucleon isobar N***(1688) has produced evidence that (1) N***(1688) is a member of a unitary octet, and (2) the D/F ratio, which relates the couplings N***N π and N***Nn, is similar to that which relates NN π and NNn.
