Abstract
The β+ spectra of neutron-deficient nuclei with mass numbers 103 and 104 have been measured, using a semiconductor beta spectrometer. The nuclei were produced by on-line mass separation of reaction products formed by bombarding an enriched Mo target with Ne ions. Values for QEC have been deduced. The decay energies are in agreement with systematics. The decay of104In shows remarkably strong feeding to levels above 5 MeV. In addition, QEC values for103Cd,103Ag,104Ag and104mAg have been determined.
