“…2,3 In the process Fox et al 4 noticed a curious cycle pattern for clusters of levels belonging to octahedral-group (O) irreducible representations (IR's) that appeared in the splitting of each J manifold. A cycle of four sixfold, nearly degenerate clusters (A lf E, T x ), (7\, T 2 ), (A 2 , E, T 2 ), and (T 19 T 2 ) may be repeated several times in the upper limb until it abruptly splits and forms a similar cycle of eightfold clusters (£, T 19 T 2 ), (A 19 A 29 T 19 T 2 ) 9 and (E 9 T 19 T 2 ). A similar clustering was noticed earlier by Dorney and Watson 5 in their XY 4 model calculations.…”
