摘要：

Manganese centers were investigated in silicon specimens with initial doping concentrations between 1.5 x 10(15) P cm(-3) and 6X10(15) B cm(-3). All known Mn centers could be observed but the cluster Mni3Mni was missing in highly-boron-doped material, indicating that this center is negatively charged. A new center of trigonal symmetry was observed for an initial doping of 6 X 10(15) B cm(-3) and identified as a Mn-i3(2+) cluster. The EPR signal of this center is strongly light sensitive in contrast to the other known Mn clusters.
