“…Such a very noticeable quenching of favoured GT transitions shows up as a characteristic feature of the beta decay of heavier nuclei. It was recently studied for the ~hl 1/2 ~ vh9/2 transitions [4][5][6], and much earlier for the unhindered transitions between the Nilsson states originating from the h11/2 and h9/2 orbitals [7]. For lower-shell nuclei, the quenching of measured GT beta decay strengths, as well as measured magnetic moments and B(M1) values, has been extensively investigated (see e.g.…”

Using the 4~MeV/u)+6~ reaction and on-line mass separation, the decay 96 properties of 46Pdso were reinvestigated. From a comparison of experimental and theoretical fl § + fl+) probability ratios, the QEc value was deduced to be 3,450_+ 150 keV. The strength was determined for four 0+~ 1 § Gamow-Teller beta transitions and found to be quenched as compared to predictions of the single-particle shell model. For 96pd and 94Ru the sources of this quenching are discussed.

“…The deviation of the fi-strength function from a constant is the main source of systematical errors of this method. We have considered reasonable possible forms of Sa(E) and found [10] that different choices of S~(E) may change the endpoint by a value of about 100 keV.…”

“…For simplicity, the response function of a single 7-quantum was practically represented as a 6-function and a Compton tail. The effect of the finite energy resolution of the spectrometer on the experimental Q-values was considered independently [10]. It was found that some smearing out of the spectra due to the finite energy resolution results in overestimation of Q-values.…”

“…Another approach for the determination of 7-ray endpoints, used in our works [5][6][7], and based on the measurement of the total 7-absorption (TGA) spectra is practically free of these deficiencies. In fact, the highenergy parts of TGA spectra represent actually the ecapture branches to the states close to Q~, provided the total energy peak efficiency is sufficiently high.…”
