Abstract
The production of the isoscalar Jp = 3+ didelta dibaryon d* by proton inelastic scattering from deuteron targets is described in a double-scattering Glauber approximation. Each scattering changes a target nucleon into a Delta with the help of the isovector tensor force transmitted by pi and rho mesons. The differential cross section constructed from empirical Love-Franey nucleon-nucleon t-matrices and a simple model of d* shows a maximum of some 10 micro-b/sr at 70 deg (c.m.) for 500 MeV protons. The partial width of the decay d* -> NN caused by the exchanges of the same mesons is found for this simple model of d* to be about 9 MeV if the d* mass is 2100 MeV. The implications of these results are discussed.
