Nuclear Data Sheets for A = 241

Available information pertaining to the nuclear structure of ground and excited states for all known nuclei with mass numbers A=241 have been compiled and evaluated. The adopted level and decay schemes, as well as the detailed nuclear properties and configuration assignments based on experimental data are presented for these nuclides. When there are insufficient data, expected values from systematics of nuclear properties or/and theoretical calculations are quoted. Unexpected or discrepant experimental results are also noted. A summary and compilation of the discovery of various isotopes in this mass region is given in 2013Fr02 (²⁴¹Np, ²⁴¹Pu, ²⁴¹Am, ²⁴¹Cm, ²⁴¹Bk, and ²⁴¹Cf), 2011Me01 (²⁴¹Es), and 2013Th02 (²⁴¹Fm).
