We calculate the relativistic corrections of J/{psi}, including electromagnetic corrections, to {chi}{sub b}J{yields}J/{psi}J/{psi} in the framework of nonrelativistic QCD factorization. The relativistic effects are found to increase the lower-order prediction for the decay width by about 10%, while the electromagnetism contribution is very small, about 0.2% for {chi}{sub b0} and {chi}{sub b2}. The total branching ratios are predicted to be of order 10{sup -5} for {chi}{sub b0,b2}{yields}J/{psi}J/{psi}, but 10{sup -11} for {chi}{sub b1}{yields}J/{psi}J/{psi}, since there is only electromagnetism contribution in this channel. We predict it is possible to observe these reactions in LHC.
