Title: Energy levels of neutral and singly ionized berkelium, /sup 249/Bk I and II

Energy-level analyses of the observed emission spectrum of berkelium have yielded 179 odd and 186 even levels of neutral berkelium Bk I, and 42 odd and 117 even levels of singly ionized berkelium Bk II. The levels are tabulated with the J value, the g value, the configuration and hyperfine constants A and B, and the width given for many of the levels. The ground states of Bk I and Bk II are (Rn)5f/sup 9/7s/sup 2/ /sup 6/H/sup 0//sub 15/2/ and (Rn)5f/sup 9/7s /sup 7/H/sup 0//sub 8/, respectively. A table lists the lowest level of each identified electronic configuration of Bk I and Bk II.
