I am currently studying TL, OSL, EPR and stimulated electron dating in general. I read some accounts of the physics behind it (I am no physicist) which, though complex, seem pretty well established to me. However, around one year ago, talking to a student in a TL lab, it came out that the theory behind stimulated electron dating is still under discussion. Is that true? would anyone be so kind to provide some references?
I have another related question. For stimulated electron dating to be valid an annual dose of radiation must be measured: how do we know that it hasn't changed over time, since the zeroing event?
Please note that theory of TL etc is phenomenological. There is no TL theory or models based on first principles, however the phenomenological theory works well in predicting fading, dose linearity and response and other features of TL glow curves. There is no absolute theory and assumptions need to be set for each glow curve in a given material.
Thank you very much for your answer @Munish Kumar. Could you suggest some bibliography highlighting this aspect of the theory?
