Beta-delayed neutron emission is being studied by detecting the particles and recoiling ions emerging from the Beta-decay Paul Trap. For decays to the ground state or γ-emitting states of the daughter nucleus, the fraction of recoiling ions which reach the ion detector in coincidence with a particle has been determined for ^{134, 135}Sb, ^{137, 138, 140}I, and ^{144, 145}Cs. This value is needed for the determination of the -delayed neutron emission branching ratio solely from the recoil-ion time-of-flight (TOF) spectrum. The β-particle energy and recoil-ion TOF spectra were used to constrain a simple decay model, which can be used to determine the detection efficiency. The method is compared to simulations to estimate the uncertainty introduced by incomplete knowledge of the decay pattern. By fitting the simulation results to several β-ion coincidence properties measured during the experiment, the fraction of ions which reach the microchannel plate detector can be determined to within ±4%. In conclusion, this result opens the possibility of using the recoil-ion TOF spectra for high precision β-delayed neutron branching-ratio measurements.

Experimental data on ground- and excited-state properties for all nuclei with mass number A=144 have been compiled and evaluated. States populated in radioactive decay as well as in nuclear reactions have been considered. For these nuclei, level and decay schemes have been built, as well as tables of nuclear properties. This work supersedes the 1989 evaluation by J.K. Tuli (1989Tu02).
