198AU cL E Possible a proposed 646 level could resolve intensity
198AU2cL imbalance at the 312 level. It could be fed directly from the isomer,
198AU3cL or via a low-energy transition from 696-level. The latter is more
198AU4cL likely, and would suggest I(|g+ce)(115.2|g)=100. Neither author would
198AU5cL have seen a highly converted 50|g connecting the 696 and the possible
198AU6cL 646 level. Unplaced 333.82|g could be placed between 646 and 312
198AUxcL levels.
