Which of the following is the relatively most accurate method for dating of fossils?
- radio-carbon method
- potassium-argon method
- electron-spin resonance method
- uranium-lead method.
Solution
Electron spin resonance dating is a technique that can directly detect unpaired or odd electrons in atomic or molecular systems. In this technique, a static magnetic field and microwaves are used to observe the behavior of the unpaired electrons in the material being studied. The study of the behavior of the electrons in a sample gives information about the condition of the sample.
