## Description

Title of program: EIGLAB Catalogue Id: ABID_v1_0 Nature of problem Basis states of U(3) in the O(3) representation are required to describe certain atomic nuclear or multipion states, U(3) can refer to dynamical or permutation symmetries, O(3) to angular momentum or isospin. EIGLAB computes such states as eigenstates of an O(3) scalar labelling operator Q in the enveloping algebra of U(3).
