Optical Properties of Galaxite
Gladstone-Dale:
CI meas= -0.048 (Good) - where the CI = (1-KPDmeas/KC) CI calc= -0.095 (Poor) - where the CI = (1-KPDcalc/KC)
KPDcalc= 0.2279,KPDmeas= 0.2182,KC= 0.2081 Ncalc = 1.84 - 1.88
Optical Data:
Isotropic, n=1.923.
Calculated Properties of Galaxite
Electron Density:
Bulk Density (Electron Density)=4.07 gm/cc note: Specific Gravity of Galaxite =4.23 gm/cc.
Fermion Index:
Fermion Index = 0.0022704957 Boson Index = 0.9977295043
Photoelectric:
PEGalaxite = 9.24 barns/electron U=PEGalaxite x rElectron Density= 37.56 barns/cc.
Radioactivity:
GRapi = 0 (Gamma Ray American Petroleum Institute Units) Galaxite is Not Radioactive
