Abstract A calculation of the blackbody radiation shift of the B+ clock transition is performed. The polarizabilities of the B+2s2 1Se, 2s2p 1Po, and 2s2p 3Po states are computed using the configuration interaction method with an underlying semiempirical core potential. The recommended dipole polarizabilities are 9.64(3)a03, 7.78(3)a03 and 16.55(5)a03, respectively. The derived frequency shift for the 2s2 1Se → 2s2p 3P0o transition at 300 K is 0.0160(5) Hz. The dipole polarizabilities agree with an earlier relativistic calculation [Safronova et al., Phys. Rev. Lett. 107, 143006 (2011)] to better than 0.2%. Quadrupole and octupole polarizabilities and nonadiabatic multipole polarizabilities are also reported.
