Abstract : The radiations of Zr(97) and Nb(97) and Nb(97) were examined by beta-ray spectrometry and coincidence counting. The 17.0-hour Zr(97) was found to decay to a 60-sec. isomer of Nb(97), the latter undergoing isomeric transition to the 75-min. Nb(97) ground state. The disintegration energies are; Zr(97), E-Beta = 1.91 + or - 0.02 Mev.; Nb(97)m, E-gamma = 0.747 + or - 0.005 Mev.; Nb(97), E-beta = 1/267 + or - 0.02 Mev.; E-gamma = 0.665 + or - 0.005 Mev.
