Experimental nuclear structure data from various reactions and decays are compiled and evaluated for all known nuclides with mass number A=48 (S, Cl, Ar, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni). For each nuclide, detailed evaluated nuclear structure information is presented for each individual reaction and decay, and the best values combining all available data are recommended for spectroscopic properties, such as level energies, half-lives, γ-ray energies and intensities, decay radiations. No excited states have been identified in 48S, 48Cl, 48Co and 48Ni, among which the first three even have no measured ground-state half-lives and decay modes. For 48Fe, a level scheme with a sequence of excited states was established for the first time from a recent one-neutron removal measurement by 2021Ya33. Data for excited states in 48Ar, 48K and 48Mn remain limited; no decay scheme has been measured for 48Ar and 48K yet, while the decay scheme for 48Ni is incomplete due to unobserved levels. 48Ti is the most studied nuclide through various reactions and decays, followed by 48V, 40Ca, 48Sc, and 48Cr, among which no decay event to 48Sc has been observed and the decay schemes for 48V and 48Cr are considered as incomplete. This work supersedes the previous full evaluations of A=48: 2006Bu08, 1993Bu04, 1985Al14, 1978Be01.
期刊介绍:
The Nuclear Data Sheets are current and are published monthly. They are devoted to compilation and evaluations of experimental and theoretical results in Nuclear Physics. The journal is mostly produced from Evaluated Nuclear Structure Data File (ENSDF), a computer file maintained by the US National Nuclear Data Center
