IBM: parameter symmetry, hidden symmetries and transformations of boson operators
A. M. Shirokov, N. A. Smirnova, Yu. F. Smirnov +2
A symmetry of the parameter space of interacting boson models IBM-1 and IBM-2 is studied. The symmetry is associated with linear canonical transformations of boson operators, or, e…

Can one learn anything from proton-proton bremsstrahlung? Comment on H. W. Fearing preprint nucl-th/9710061
D. L. Pursey, A. M. Shirokov, T. A. Weber
Recently, Fearing (nucl-th/9710061) has argued that, as a matter of principle, proton-proton bremsstrahlung can yield no more information about the off-shell properties of the nucl…
