Fine Structure in Proton Emission from 145Tm Discovered with Digital Signal Processing
Abstract
Fine structure in proton emission from the 3.1(3) μs activity of
145Tm was discovered by using a novel technique of digital processing of overlapping recoil implantation and decay signals. Proton transitions to the ground state of
144Er and to its first excited 2+ state at 0.33(1)MeV with a branching ratio Ip(2+)=9.6±1.5% were observed. The structure of the
145Tm wave function and the emission process were analyzed by using particle-core vibration coupling models.
