    Notes: Abstract The beta and gamma radiations of237Pa have been investigated employing semiconductor and scintillation spectrometers and coincidence techniques. Sources of237Pa were obtained after bombardments of238U with bremsstrahlung and 14-MeV neutrons and subsequent chemical separation. From the total of 18γ-rays following the decay of 8.7±0.2 min237Pa 17 transitions, representing 99.9% of theγ-ray intensity, could be placed in a level scheme of237U. AQ β- value of 2.25±0.1 MeV has been determined.

    Notes: Abstract The decay properties of the neutron deficient isotopes73–77Kr and73–76Br have been studied at the ISOLDE facility at CERN. The total decay energiesQ, as determined fromβ + singles orβ + -γ coincidence measurements, are compared with mass formulae.

    Notes: Abstract The beta and gamma radiations of163Tb have been investigated employing scintillation and semiconductor spectrometers and coincidence techniques. The sources were produced by the163Dy(n,p)163Tb reaction. A half-life of 19.5 min has been measured without evidence for an isomeric state in the half-life range of 2 sec to 7 d; especially a 6.5 h activity previously assigned to163Tb could not be confirmed. 76 of the total of 82 gamma-ray transitions, representing 99.6% of the gamma-ray intensity, could be assigned to 23 levels in163Dy. From beta and beta-gamma coincidence measurements aQβ-value of 1.7 ± 0.1 MeV has been determined. Spin and parity of 3/2+ are deduced for the ground state of163Tb with the Nilsson configuration [411↑]. The level at 884 keV is interpreted as aJ π=1/2+ state with a high contribution of the three-quasiparticle configurationp[411↑]-p[523↑]-n[523↓] because of an allowed unhindered beta-ray transition to this level.
