“…(see Table 1). The NO result of Barclay et al [1][2][3][4][5][6][7][8][9][10][11][12][13][14] differs from the NMR-ON value by ~12%. As can be seen from Table2, the E2/M1 mixing ratio differs, too.…”

Angular distributions have been measured for 7-rays emitted following the decays of 97'~~176 oriented in an iron matrix at temperatures down to 2.8mK. From the temperature dependence of the 7-anisotropies the magnetic hyperfine splitting frequencies vM= Ig#NBHF/hl of 97, lo3, lO~RuFe were found to be 110(7), 57 (15) The analysis for a~ has been performed with the assump--0.13" tion of j~=3/2 + and 5/2 + for the ground state of l~ Taking into account experimentally known g-factors of 3/2 + and 5/2 + states in this mass region, our data strongly favour the assignment j~= 3/2 + for the l~ ground state.

Abstract. The/?--decay of 7.6-min l~ has been investigated by/?-and 7-ray singles and coincidence measurements. The activities have been produced by thermal-neutron-induced fission of/3sU or 239pu and subsequent chemical separation of the technetium fraction from the fission product mixture. A Qp-value of 3.2_+ 0.2 MeV has been determined. In a delayed coincidence experiment the lifetime of the first excited state in t~ at 20.55 keV has been measured to be 340_ 15 nsec. A level scheme of 10SRu is proposed and compared with the results of recent nuclear reaction studies like ~~ p) and l~ 7). From beta branching ratios to levels in l~ ground state spin and parity of 5/2 + can be suggested for ~~ in accordance with the trend observed in neutron rich technetium isotopes.

“…The spectrum of 7-rays emitted by l~ is well established by the work of Zoller, Macias, Perkal and Walters [7]. The decay of l~ is well understood from the work of Schriber and Johns [8] and the decay of 95Tc has been summarized by Medsker and Horen [9]. Spectral features labelled B are present in the environmental background while those labelled R were found to be present in a residual spectrum obtained after the 1~ had decayed to negligible proportions.…”
