In an experiment to understand why a two-level system cannot act as a laser, a student heated the gas inside began looking at a spin system with only two energy states -μH and μH corresponding to parallel alignment and anti-parallel alignment respectively with the magnetic field H. In Ins measurements of ratio of number of spin up to spin down particles as he increased the magnetic field he finds that it never exceeds a number α. What is α? ( answer must be given upto 2 decimal places)
    Correct answer is '1'. Can you explain this answer?
