← ScienceWhich outcome results when high-energy particles impact a crystalline scintillator?
A)Photon emission via electron relaxation✓
B)Phase transition to amorphous structure
C)Increased electrical conductivity marginally
D)Decreased thermal expansion coefficient slightly
💡 Explanation
Photon emission occurs because the Scintillation mechanism involves impacted particles exciting electrons; these then relax and emit photons. Therefore light flashes are emitted, rather than marginal conductivity increase or phase change effects under normal operating conditions.
