Abstract
The decay of140Pr was investigated by means of a Ge(Li) spectrometer. Excited states of140Ce at 1,596.2, 1,903.1, 2,348.9, 2,522.5, 3,016.8 and 3,119.6 keV are fed in the beta decay of140Pr. Spin and parity assignments for all observed levels have been made from electron capture and positon disintegration considerations and gamma branches. The experimental level scheme of140Ce is compared with the results of shell model calculations forN=82 nuclei.
