Two nucleon t-matrices, on- and half off-shell, of experiment and theo
ry are used to put expectations into new Bremsstrahlung experiments on
a realistic basis. A report is given about comprehensive studies of p
p Bremsstrahlung which includes a reanalysis of TRIUMF data and other
data of non coplanar geometry experiments. The Bremsstrahlung amplitud
es associated with external, rescattering and exchange currents, by ex
act treatment of the Coulomb potential in on- and half-off-shell t-mat
rices, and the relativistic spin corrections were all computed and for
both coplanar and non coplanar geometries.
