The beta-decay of 232Fr to excited states in 232Ra has been studied using gamma-gamma coincidence detection combined with the isotope separator on-line technique at the ISOLDE PSB facility at CERN. Earlier findings are confirmed and three new gamma lines are reported. In addition to the beta-decay characteristics of 232Fr, the K = 0 ground-state band in 232Ra is identified. A yield survey of neutron-rich Fr isotopes, important also for the EURISOL project, is incorporated.
