Abstract: The E1 transition from the 3/2^- state to the ground state of ²²⁹Pa was identified in the (p,t<Gamma>) reaction. Its energy is found to be 11.6(3) keV. This leads to a value of Q_g.s. = -4133(2) keV and to a mass defect of ²²⁹Pa of 29894(3) keV. It is concluded that the ground-state configuration of ²²⁹Pa is 3/2[651].
