Abstract
Based on the [eta\ representation, which is the common eigenvector of two p
articles' relative coordinates and total momentum, we derive the common eig
envector \q, k] of the charge operator Q = a dagger a - b dagger b and (a d
agger - b)(a - b dagger) as well as charge raising (lowering) operators. Th
e \q, k] set is complete and orthonormal. (C) 1999 Published by Elsevier Sc
