Abstract

We have measured the wavelength of 30,789 transitions in Pu with the 9.15-m Paschen–Runge spectrograph at Argonne National Laboratory and the Fourier-transform spectrometer at Laboratoire Aimé Cotton. More than 52% of these transitions have been classified. For the neutral atom 606 even-parity and 586 odd-parity levels have been identified. The total angular momentum has been assigned to all the levels, and for most levels the Landé g factor and isotope shift have been measured. Eight even and six odd electron configurations have been identified. The dominant electronic configuration and term have been assigned to about half of the Pu i levels.
