Integral equations and the bound‐state problem
An integral equation for the s‐wave bound‐state solution is derived and then solved for a square‐well potential. It is shown that the scattering solutions continue to exist at negative energies, and when evaluated at the energy of a bound state these solutions do reduce to the bound‐state solution. The bound‐state energies of a square‐well potential are deduced also from orthogonality considerations. Finally, the existence of bound states for an arbitrary short‐range potential is related to the occurrence of zeros of the Jost function or poles of the S matrix for that potential.

Radiative processes of UPSILON and UPSILON' and off-shell suppressions
Within the framework of an extended vector-dominance scheme, the various radiative processes of UPSILON and UPSILON' are studied. The rates turn out to be generally much smaller than those of the corresponding psi decays and in some cases too small for direct observation. The off-shell UPSILON-..gamma.. and UPSILON'-..gamma.. coupling constants are found to be suppressed by about a couple of orders of magnitude compared with their on-shell values.
