Gamma-gamma angular correlation studies in97Tc

“…However, the angular correlation result is in accordance with both a 5/2 + and a 7/2 + assignment. Using 6(215.7) =0.20(5) and A 2 =0.01(2) we get 6(754.0)= 19+~ 5 or -0.16(2) for the alternative U=5/2 + while the assignment U = 7/2 + gives 6 (754.0) = -3.9(7) or 0.53 (6). The A4-value is consistent with all these mixingratios.…”

“…The mixing-ratio of the 108.8 keV transition as a function of the mixing-ratio of the 215.7 keV transition with A2=0.38(3 ). The ranges for 6(108.8) and 6(215.7) as determined by Bergman et al [6] are also included in the figure (a and b respectively) result of Bergman et al with a negative sign and the range allowed for the 3(215.7)-value by the present A2-coefficient even if two standard deviations are allowed for both in the A2-coefficient and the g-value.…”

“…The [1]. The halflives determined by Bergman et al [6] have also been included sample was dissolved in sodiumhydroxide and sodiumhypochlorite as above but no HC1 was added. Instead the ruthenium was allowed to reduce on paraffin paper to RuO 2.…”

“…Both transitions are thus a mixture of E2 and M1 multipolarities. The E2 contents have been determined from a measurement of L-subshell intensity ratios by Bergman et al [6]. ..--6(215.7) Fig.…”

“…This has been achieved by studying the decay of 97Ru, t 89 with different techniques. High-resolution gamma-spectroscopy [1][2][3][4][5], electron conversion studies [2,3,6] and measurements of the half-lives of the two lowest excited states [6,7] have given important information. Through nuclear reaction studies [8][9][10][11] additional information was obtained.…”
