Known problems/ missing topics date date who description found fixed 5-Nov 98 GF String models need projectile momentum along +z; G4VPartonStringModel should do this rotation. Nov98 Above is wrong. for the excitation the transformation to the correct frame is done. 5-Nov-98 GF G4VPartonStringModel must use momentum corrector Do not forget Nucleus in this. 9-Dec98 Done. Nucleon momenta are included by correcting to sum of strings; these were checked to conserve E/p. 30-Oct GF dtor of G4VPartonStringModel should delete things; Or should derived classes actually do this?
