Abstract

The beta decay energy Qβ of the delayed neutron emitters 49,50K produced by fragmentation of a uranium target with a 600 MeV proton beam has been determined. Energies of the beta transitions to well-located neutron emitting levels in the daughter nuclei have been measured by means of a scintillation telescope in coincidence with a large solid angle neutron time of flight spectrometer. The K49 and K50 inferred mass excesses, -30.33±0.07 and -25.5±0.3 MeV, respectively, are compared with mass predictions.
