Portions of the spectrum of several double negative ions X 2− have been explored to see whether any bound states exist; the results suggest that none do. In the process, the position of the lowest 2 S 0 state in Li I, configuration 2 p 2 3 p was found. For He − , the positions of several resonances lying just below the n = 3 thresholds and the thresholds themselves have been determined and compared with features detected earlier by Roy. Finally, an accurate correlated charge density has been constructed for the ground state of the neutral neon atom, which is being used to test a local density model proposed by Vosko et al.
