Classification of the single excited SU3-states in heavy nuclei

The method of classification of the singly excited SU3-states in heavy nuclei taking into account the Pauli principle has been discussed and adapted to finding irreducible representations of the SU3-group with the largest eigenvalue of the square Casimir operator. A table of such representations for 40 nuclei in the range of the mass number ≤ A ≤ 254 is presented. Qualified analysis of the data obtained has been carried out. The possibility of application of that classification for the interpretation of the experimental level bands of negative parity in heavy even-even nuclei has been pointed out
