Nuclear orientation study ofW182in the decay ofRe182isomers

The decay schemes of the two ${}_{}{}^{182}{}_{}{}^{}\mathrm{Re}$ isomers (64 h and 13 h) have been studied mainly with the nuclear orientation technique. New information, especially on the high-spin states of ${}_{}{}^{182}{}_{}{}^{}\mathrm{W}$, populated in the decay of the 64-h ${}_{}{}^{182}{}_{}{}^{}\mathrm{Re}$ isomer, has been obtained. Many spin assignments of ${}_{}{}^{182}{}_{}{}^{}\mathrm{W}$ levels have either been verified or made. Above 1500 keV spins of 14 levels have been derived uniquely or with a high level of confidence. The 64 h($7^{+}$) and 13 h($2^{+}$) isomers of ${}_{}{}^{182}{}_{}{}^{}\mathrm{Re}$ are described in terms of the coupling of the Nilsson states 5/$2^{+}$[402] and 9/$2^{+}$[624] for the odd proton and odd neutron. The experimental absolute values of their nuclear moments $\mu \left(7^{+}\right)=2.79\mathrm{}\pm 0.06{\mu }_N$ and $\mu \left(2^{+}\right)=3.11\mathrm{}\pm 0.33{\mu }_N$ are well understood on the basis of this coupling.
