“…Lines with intensities greater than 1.5% relative to the 302.5keV transition were observed in the present work.

In general the agreement is good except for the 511.2 keV transition, which appears to be dubious.…”

Abstract. Short lived Ru isotopes produced in thermal fission of 235U have been chemically separated from the other fission products. Successive y-ray spectra were taken by means of Ge(Li) detectors. The observed v-lines have been assigned to the various Ru isotopes (A = 107 to 110) or to their daughter elements on the basis of their half-lives, intensity ratios and known level properties. Partial decay schemes are discussed and relative fission yields are given, mRu has been identified (T1,2:1.5_+0.3 s).

“…Figure 2 shows the y-ray spectrum of the ruthenium fraction (organic phase) after the solvent extraction. Most of the y-ray peaks can be assigned to the ruthenium nuclides with mass number 107, 108, 109, 110, 111 and 112 or their daughters as given in the literature [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. 107 Ru Table 2 gives the decay data on the y-rays following the ß~ decay of 107 The absolute intensities, Iy in Table 2, were obtained by taking into account the y-ray yields of 252 Cf fission given by Wilhelmy [24] and the cumulative yields for the ruthenium nuclides by Rider [27].…”

The short-lived ruthenium nuclides produced in the spontaneous fission of 252 Cf were separated from the fission products mixture by SISAK coupled with a KCl/He gas-jet recoil-transport system and y-rays were measured on-line after a single extraction step. The energies and intensities of the y-rays following the β' decays of 107 ~ 112 Ru were determined. 0.2M H2S04 0.2M H2S04 5X10~5M RuCl, 0.015M Ce(S04)2 Fig. 1.
