Comment on Algebraic analysis of physical and spurious states in Dyson boson mapping

Hahne F.J.W. ; Geyer H.B. ; Engelbrecht C.A. (1988)


By stressing the application of boson mapping techniques to the truncated collective branch of nuclear excitations, the usefulness of two recently developed methods for the treatment of spurious states are compared. It is shown why the identification proposed by Geyer et al. is superior to the use of the Majorana operator S as proposed by Park. © 1988 The American Physical Society.
