C 98, 024612 (2018) V.Rakopoulos, M.Lantz, A.Solders, A.Al-Adili, A.Mattera, L.Canete, T.Eronen, D.Gorelov, A.Jokinen, A.Kankainen, V.S.Kolhinen, I.D.Moore, D.A.Nesterenko, H.Penttila, I.Pohjalainen, S.Rinta-Antila, V.Simutkin, M.Vilen, A.Voss, S.Pomp First isomeric yield ratio measurements by direct ion counting and implications for the angular momentum of the primary fission fragments NUCLEAR REACTIONS U, 232Th(p, F)81Ge/81mGe/96Y/96mY/97Y/97mY/128Sn/128mSn/130Sn/130mSn/129Sb/129mSb, E=25 MeV; measured fission fragment time of flight, mass, isomeric yield ratios using JYFLTRAP for fragment separation and microchannel plate for particle detection at IGISOL-Jyvaskyla facility. Comparison with theoretical calculations of fission fragment isomeric yield ratios and rms spin of fragments using GEF code and TALYS code with constant temperature Fermi gas model, back-shifted Fermi gas model (BSFG), and the microscopic level densities of Goriely. Comparison with previous experimental values.
