d*(2380)+X with n=1,2,3 are studied in a phenomenological way. With the help of crossing symmetry, the decay widths are obtained by investigating the imaginary part of the forward scattering amplitudes between d* and Υ(nS). The wave functions of m d* and deuteron obtained in previous studies are used for calculating the amplitude. The interaction between d* (d) and Υ is governed by the quark-meson interaction, where the coupling constant is determined by fitting the observed widths of Υ(nS)→d+X. The numerical results show that the decay widths of Υ(nS)→d*+X are about 2-10 times smaller than that of d+X. The calculated momentum of d* is in the range 0.3-0.8 GeV. Therefore, it is very likely that one can find d*(2380) in these semi-inclusive decay processes."> Phenomenological study on the decay widths of Υ(<em>nS</em>)→d<sup>*</sup>(2380)+X<sup>*</sup> -
