“…The earlier reported e-line of 5.372MeV of ~6VRe Ell, 12] and of 5.136MeV of 16SRe [12] were later ascribed to 166Re, and 167Re, respectively [9]. A further complication arises from the fact that the tungsten isotopes 163-~65 W are known to have similar e-ray energies of 5.384, 5.148, and 4:902 MeV [13,14] and half-lives being close to those reported for the rhenium isotopes. Therefore, we performed a careful investigation of this region.…”

The neutron-deficient rhenium isotopes 166-17~ were investigated using reactions of 32S with monoisotopic 141pr targets. Gamma-rays following the fl-decays of 166-169Rewere measured for the first time. Four new e-rays with energies of 4.70, 4.83, 4.87, and 5.02 MeV were detected in addition to the known 5.50, 5.26, and 5.06 MeV e-rays. Alpha-decaying isomer pairs were discovered in 167Re and 169Re. The measured half-lives are 2.3(2)s for 166Re, 3.4(4)s and 6.2(5)s for 167Re, 4.4(1)s for 168Re, 8.1(5)s and 16.3(8)s for 169Re, and 9.2(2)s for iV~ The nuclear structure is discussed in terms of single-particle states.

“…For later half-life measurements chemical separations of tungsten were performed by adsorbing lanthanides, Ta and Hf on a DOWEX 50X8 (200-400 mesh) column saturated with La(OH) 3 and using a 0.1 M NaOH solution as eluent. Under these conditions the tungsten fraction passed the cation exchange column and could be adsorbed on a following DOWEX 1X8 (200-400 mesh) column.…”

“…However, these reactions would only affect the absolute values of the cross-sections and not alter the position of the maximum of the excitation functions or their shapes. Eastham et al pointed out [3] that the pxn-channels peak at nearly the same energies as the (x + l)nchannels.…”

“…Fig. 1, shows the results in relative cross-sections together with a fit through the experimental data from Eastham et al [3] from the same nuclear reaction. Both experimental data sets for 164 W are in a reasonable agreement.…”

“…Unfortunately, only few data on these two exotic nuclei are available from the literature. Eastham et al [3] W were first produced by Toth et al [4] in the reaction ,56 Dy ( 16 0, xn). Additional data on 16°-,66 w reported in [5,6] were confirmed by these authors.…”
