    "abstract": "We demonstrate that decoherence of many-spin systems can drastically differ\nfrom decoherence of single-spin systems. The difference originates at the most\nbasic level, being determined by parity of the central system, i.e. by whether\nthe system comprises even or odd number of spin-1/2 entities. Therefore, it is\nvery likely that similar distinction between the central spin systems of even\nand odd parity is important in many other situations. Our consideration\nclarifies the physical origin of the unusual two-step decoherence found\npreviously in the two-spin systems.",
