Primary and secondary masses of heavy reaction products have been deduced f
rom kinematics and E-ToF measurements, respectively, for the direct and rev
erse collisions of Nb-93 and Sn-116 at 25 AMeV. Light charged particles hav
e also been measured in coincidence with the heavy fragments. Direct experi
mental evidence of the correlation of energy-sharing with net mass transfer
has been found using information from both the heavy fragments and the lig
ht charged particles. The ratio of hydrogen and helium multiplicities point
s to a further correlation of angular momentum sharing with net mass transf
er.
