dc.descriptionWe compare the virtues of two options for the isospin (I=1 or 2) of the apparently exotic dibarion resonance d_1^*(1956), as it is noticed by the DIB2gamma Collaboration (JINR) in the reaction pp -> 2 gamma X below the pion threshold, and using recent results following from the RMC Collaboration (TRIUMF) measurement of the relative probability of the double-photon pion capture in the pi-mesic deuterium atoms.
