“…In this experiment, 25 isomeric ratios have been determined and five of them for the first time. The new ratios belong to isomers in 90 Nb [43][44][45], 92 Nb [45,46], 94 Rh [47], and 96 Cd [24]. The experimental values from this work can be found in the third column of Table II.…”

A systematic study was performed of microsecond γ-decaying isomers around 100 Sn produced in a fragmentation reaction of a 124 Xe beam at 345 MeV/u at the Radioactive Ion Beam Factory of the RIKEN Nishina Center in Saitama, Japan. Half-lives of isomeric states in that region were remeasured allowing us to improve the currently available experimental information. Reduced transition probabilities were deduced and compared to shell-model calculations in various model spaces. The recently reported low-energy transitions in 92 Rh and 96 Ag were remeasured with improved precision. Additionally, experimental information on isomeric ratios, including five new ones, were extracted and compared to a previous experimental study and the sharp cutoff model of fragmentation reaction.

“…The same was allowed to decay to ensure that the dead time of the detecting system would be less than 5%. Self absorption corrections were made at different energies using the following relationship (13). The system was calibrated for energy and efficiency using the standard lines from la3Ba, Z41Am and 15ZEu.…”

The total conversion coefficient of the 127.49 keV E3 isomeric transition in the decay of 134mCs was measured using the gamma intensity balance method with the help of a high resolution low energy photon detector. The er value was found to be 5.84_+0.47 as against the theoretical value of 6.96, thus showing an anomaly of (16.1 +6.7)%. The K-conversion coefficient, ~ was also measured using the X-ray peak to gamma ray intensity method and found to be 2.24+0.04 as against the theoretical value of 2.72, which shows an anomaly of (17.6_+ 1.4)% consistent with the experimental anomaly in at-The E 3 hindrance factor of the isomeric transition was estimated to be (3.44 _+ 0.23) 9 10 4.

7-spectra and excitation functions of the ~~176 nT) l~176 reaction were measured in the 1.2-3.6MeV proton energy range by using thick, enriched targets, Ge(Li) and low energy photon (hyperpure Ge) spectrometers. These detectors were used in YTcoincidence experiments, too. Conversion electron spectrum measurements were performed by means of a superconducting magnet transporter Si(Li) spectrometer (SMS) at Ep =4MeV and multipolarities of some transitions have been determined. Based on the experimental results a level scheme of l~176 has been constructed. Level energies of l~176 were calculated on the basis of the parabolic rule, derived from the cluster-vibration model.Nuclear Reaction: l~176 nT), E= 1.2-4.0 MeV.
