“…Therefore, already from these arguments, strong lines in the spectra not attributable to these nuclei should belong with high probability to 1~ That ~~ is indeed strongly populated in our reaction, can be seen from the strong residual activity observed from the /#decay of ~~ Figure 4 shows a ?,-spectrum taken over ten minutes after irradiation of 9~ by 72MeV 19F ions (added over several cycles), Evidently, the strongest lines in this spectrum belong to the 6.4min /~+-dccay of 1~ (compare to the recent /~-decay study in Ref. 10), in agreement with the expectation from the statistical model calculations (Fig. 3).…”

“…From earlier in-beam ?,-spectroscopic investigations of ~~ [17][18][19], 1~ [15,20], l~ [21], l~ [22] and 1~ [23], it was possible to safely identify )'-transitions belonging to these nuclei. Therefore, already from these arguments, strong lines in the spectra not attributable to these nuclei should belong with high probability to 1~ That ~~ is indeed strongly populated in our reaction, can be seen from the strong residual activity observed from the /#decay of ~~ Figure 4 shows a ?,-spectrum taken over ten minutes after irradiation of 9~ by 72MeV 19F ions (added over several cycles), Evidently, the strongest lines in this spectrum belong to the 6.4min /~+-dccay of 1~ (compare to the recent /~-decay study in Ref.…”

“…There are, however, almost no investigations of odd-odd nuclei in this mass region, except two recent studies of 1~176 [4,5]. The present work is part of an investigation of yrast lines in light nuclei near the closed shells Z--20, N =20, (34C1, 37C1, 4~ 42Ca) and Z=28, N=28 (SSFe, S6Fe) [6][7][8], Z=50 [9] and of the //+-decay of high spin isomers in neutron-deficient nuclei with masses A~100-110 [10]. Results are given of an investigation of high spin states in ~~ by the reaction 9~ 3n).…”

“…While usually for even-even nuclei the data on the //+-decay of the odd-odd parents yield a good starting basis for the interpretation of in-beam 7-spectroscopic results of heavy ion reactions, because in these cases low-lying high-spin states undergo //-decay (see, e.g. [10]), in the case of odd-odd nuclei * Guest from the Institute of Nuclear Research of the Ukrainian Academy of Science, Kiew, USSR the situation is less favourable. So, the even-even nucleus 1~…”

“…was given recently to be 75+22 keV [2] and 2+10 keV [3], both references assuming the 58 min state to be the ground-state in accordance with the * Hiroshima University, Japan above mentioned terminology. In view of the discrepancies between various values published for spins and magnetic moments of these two states [4][5][6][7][8][9], hyperfine structure (HFS) and isotope shift (IS) measurements are of evident interest.…”
