Mechanism of the arch behaviour of charge radii in the Fayans pairing

Abstract: Arch behaviour of charge radii of Ca isotopes has been a long standing problem in nuclear theory [1–6]. Recently, it was proposed that the Fayans pairing is a possible solution to obtain it using nuclear density functional theory [2, 7]. In this talk, we will explain the mechanism why the Fayans pairing can show the arch behaviour [8].
