CALB-DET=/ Calibrations of the time for the ToF system and the energy
for the SSD were performed by measuring the elastically
scattered 16O and 18O ions from a 209Bi target, and also
the particles recoiling out from thin targets, natural Ag,
natural In, natural Sb by bombardment of the 350 MeV 127I
beam. /;
