Experimental Level

An experimental level scheme has been determined for 147Pm from an investigation of the decay of 147Nd which employed a high resolution Ge(Li) detector and a sum-coincidence spectrometer with fast-slow coincidence. Conclusive evidence is presented for the existence of levels in 147Pm at 182,228�5,275,319�5 and 725 keY besides the six already established levels, while no evidence is found for another six levels suggested by some earlier workers. Thirty-two y-ray transitions and their cascade relations have been established, and relative intensities have been determined for most of the transitions.

Gamma Transitions

Gamma transitions following the decay of 75Se have been studied using a Ge(Li) detector and a NaI(Tl)–NaI(Tl) sum-coincidence spectrometer, used in conjunction with a slow-fast coincidence circuit. Two new gamma rays of energy 373.5 and 556.4 keV have been observed and confirmed in the level scheme of 75As. Ambiguous gamma transitions of 249.2, 468.6, 542.2, and 821.6 keV energies have also been confirmed. No evidence was found for the existence of 269.0, 293.0, and 308.0 keV transitions. The accurate intensities for various transitions have been determined.

Nuclear level scheme permits to determine nuclear level density, gamma strength function, and to evaluate nuclear models. In comparison to light nuclei, the structure of heavy nuclei is much more complicated because of their strong deformation. In order to study nuclear level scheme, gamma – gamma coincidence spectrometer with advantages of low Compton background and the ability of identifying correlated gamma transitionshas been often used. This paper presents the first results of an experimentalstudy of level scheme of 172Yb using gamma – gamma coincidence spectrometer at the Dalat Nuclear Research Institute.

The 52.8-hour activity of Pm149 has been investigated using a high resolution beta spectrometer, a lens type coincidence spectrometer, and a scintillation spectrometer in conjunction with a multichannel analyzer. The beta spectrum was found to consist of two groups with maximum energies of 1.072 ± 0.002 Mev and 0.786 ± 0.004 Mev, and intensities of 97.1 ± 0.4% and 2.9 ± 0.4% respectively. A gamma ray of energy 285.7 ± 0.3 kev was found to be in coincidence with the 0.786-Mev beta group. No other gamma rays with intensities greater than 0.1% were found. The K conversion coefficient for the 286-kev transition was measured to be 0.075 ± 0.008. This together with the values of 6.5 ± 0.7 and 4 ± 1 obtained for the K/L and L/M conversion ratios respectively indicate that this transition is M1 in character with less than 10% E2 admixture.
