A New Symmetry of the Cluster Model

Prof. Moshe Gai, University of Connecticut, Storrs, CT
ORNL, Bldg. 6008 Large Conference Room

Symmetry has proved to be one of the most fascinating and useful aspect of Nuclear Structure, in so much that it directly relates the observed spectra to the finger prints (predictions) of the underlying symmetry. The triangular shape of 12C manifest itself in a newly discovered (D3h) symmetry that predicts the most unusual rotational bands including states with the spin sequence: 0+, 2+, 3-, 4+/-, 5- and observed for the first time in a nucleus. Such rotational bands including parity doublets states are all too familiar in molecular physics. I will describe state of the art measurements with an Optical Readout TPC and gamma beams that allowed us to study 12C with unprecedented accuracy and to continue our search for "the missing" states predicted by the Algebraic Cluster Model that employs the triangular (D3h) symmetry.
