Experimental Studies:
2008Kh10:241Fm produced and identified via the fusion evaporation reaction 204Pb(40Ar,3n). 40Ar beam with E=187-206 MeV from the UNILAC linear at GSi, Darmstadt bombarded a 204Pb target. 241Fm underwent spontaneous fission, and the evaporation residues were selected using the SHIP velocity filter and studied with a 16-strip Si detector, two time-of-flight detectors and an HPGe Clover detector. Measured Er-SF and Er-α correlated event (Er=evaporation residue), half-life and and fission branching. No isomers were found in this study
Theoretical/Systematical Studies:
2011Ad15: Calculated energies of low lying one-quasiparticle states with the microscopic-macroscopic two-center shell model approach(TCSM) the WKB approximation and Royer’s formula
Q-value: Δ(S(p))=500 and Δ(Q(α))=310 (syst, 2012Wa38).
