The radiations from Prl42 have been examined with a thin lens spectrometer. One gamma-ray was found having an energy of 1.576 Mev. The beta-spectrum is complex , the two groups observed having maximum kinetic energies of 2.154 Mev and 0.636 Mev. It is suggested that the high energy beta-group gives a transition to the ground state of Ndl42 and that the gamma-ray follows the loW energy beta-transition. The halflife was found to be 19.1 hr. The electron distribution produced by bremsstrahlung ~ due to the absorption of the beta-rays, was observed.
