The results are given of EPR experiments on electron excess color centers in X‐rayed synthetic calciumchlorapatite which is doped with fluoride ions. A comparison of the results obtained with those given in earlier papers on color centers in calciumchlorapatite and fluorapatite enables one to propose models for some of the electron excess centers observed. The centers observed in the material‐ consist of a) an electron trapped at an anion vacancy neighbored by two equivalent (or approximately equivalent) Cl− ions, b) an electron trapped at an anion vacancy neighbored by one Cl− and one F− ion, c) an electron trapped at an anion divacancy neighbored by two (nearly) equivalent F− ions.
