The end point energies of nuclear β decays have been measured with a segmented planar Ge LEPS detector using both singles and coincidence techniques. The β−γ coincidence has been performed with a segmented planar Ge LEPS and a single 10% HPGe detector. The γ ray and β particle responses of the Segmented planer Ge LEPS detector were studied using monte carlo simulation code GEANT3. The experimentally obtained β spectrum was in reasonably good agreement with the simulation results. The experimental end point energies are determined with substantial accuracy for some of the known β decays in 106Rh, 210Bi and 90Y. The end point energies corresponding to three weak branches in 106Rh →106Pd decay has been measured for the first time.
