Single phase HgBa2CuO,~ samples were annealed in flowing oxygen gas or m flowing argon gas. Oxygen contents of both samples determined by iodometric titrations indicate that the samples annealed in oxygen gas and in argon gas were respectively in over-doped and in under-doped region. Both samples we
