    Notes: Abstract The internal conversion spectrum from the decay of96Tc has been investigated using a 50 cm radius double-focussing beta-ray spectrometer. Relevant features of the internal conversion spectrum from the decay of96Nb have also been reexamined in the same way. Special interest has been focussed on investigating a proposed doublet level structure at about 2.44 MeV and higher lying levels in96Mo. Internal conversion coefficients have been obtained for most transitions by combining the measured conversion electron intensities obtained in this work with recently reported gamma-ray intensities from Ge(Li) detector measurements. A level scheme has been compiled and deduced transition multipolarities have been used for a discussion of spins and parities for the levels.

    Notes: Abstract The decay of103Ru to103Rh has been studied using a double-focussing spectrometer for the electron and negaton spectra and a Ge(Li) detector for gamma-ray measurements. TheL-conversion groups of the 40, 53, and 497 keV transitions were resolved at high resolution and unambigous multipolarity assignments were obtained for these transitions. The level scheme proposed resembles in principle that suggested by previous investigators. One essential difference is the doublet character of the state around 0.65 MeV. Tentative spin-parity values have been assigned to all levels from the deduced multipolarities and logft values.

    Notes: Abstract Transitions in146Eu and146Sm were studied using a double-focussing beta-ray spectrometer and a Ge(Li) detector. Internal conversion and gamma-ray intensities were determined. The internal conversion spectrum of the three 155, 115 and 116 keV cascading transitions in146Eu was studied for all subshells.K-,L- andM-subshell ratios were determined andE2/M1 mixing ratios were deduced for these three transitions. Intensities from theN- andO+P-shells were determined and compared to theoretical calculations. All internal conversion intensities were found to be in agreement with theoretical data for pureM1 character with smallE2 admixtures for all the three transitions. Selected parts of the internal conversion spectrum of the transitions in146Sm were restudied at 0.06% momentum resolution. This study was mainly concentrated on four transition doublets feeding and deexciting the close lying levels at 1,380 and 1,381 keV. A new transition with 702.20 keV energy was detected in the 702–703 keV transition group. Internal conversion coefficients were deduced using reported gamma-ray intensities. Multipole characters of the transitions were deduced and used as a basis for a discussion of the spins and parities of the lower lying excited states of146Sm.

    Notes: Abstract The level structure of101Ru has been investigated from the decays of101m Rh and101g Rh. For the gamma-ray measurements Ge(Li) detectors with effective volumes of 24 and 43 cm3 were used for singles and coincidence work, and several new transitions were observed. Conversion electron spectra from the101m Rh decay were investigated with a 50 cm double-focussing beta spectrometer.K-conversion coefficients were determined by combining internal conversion and gamma-ray intensities. For the stronger transitions probable multipolarity assignments have been obtained from these coefficients and also fromK/L andL-subshell ratios. All transitions observed were fitted into a decay scheme, in which tentative spin-parity assignments of all states are given.

    Notes: Abstract The internal conversion subshell intensities of the (21.529±0.014) keV transition in151Eu and the (22.494±0.011) keV transition in149Sm have been determined in a high resolution investigation using a double-focussing iron-core spectrometer. The subshell ratios yielded unambiguousM1+E2 multipole mixtures for both transitions. δ2(E2/M1) for the 21.53 keV transition was determined to be (8.8±0.7)·10−4 and for the 22.49 keV transition to be (5.5±1.2)·10−3.
