Abstract

Evidence for the proton decay of ¹⁴⁴Tm was found in an experiment at the Recoil Mass Spectrometer at Oak Ridge National Laboratory. The ¹⁴⁴Tm events were found in the weak p5n channel of the fusion reaction using a ⁵⁸Ni beam at 340 MeV on a ⁹²Mo target. The observed proton decay energies are 1.70 MeV and 1.43 MeV and the half-life ∼ 1.9μs. The decay properties suggest proton emission from the dominant πh _11/2 part of the wave function and from the small πf _7/2 admixture coupled to a quadrupole vibration.
