摘要

050221&_version=1&_userid=10&md5=a0f34c9865ff3a1ccec990bb03f817eb"> angular distributions were measured using 17 MeV tritons from the McMaster University FN tandem Van de Graaff accelerator. Reaction products were analyzed with an Enge split-pole magnetic spectrograph. New nuclear structure information is reported for each of the residual odd–odd nuclides ¹⁶⁰Tb and ¹⁶²Tb. Clear assignments can be made for the 050221&_version=1&_userid=10&md5=bfc3c88aa51b244769db7b51c7926394" title="Click to view the MathML source">K=1 and 050221&_version=1&_userid=10&md5=fff9f37e3f0a2e740fa61fdd8b65e10a" title="Click to view the MathML source">K=4 bands formed by coupling the 050221&_version=1&_userid=10&md5=257af843501ae24a89fba597d550d39a"> proton with the 050221&_version=1&_userid=10&md5=410064ce3481fb8a55379099d022c651"> neutron of the ¹⁶¹Dy target and with the 050221&_version=1&_userid=10&md5=72d377be4df6cc20eafcc6e32e90df71"> neutron of the ¹⁶³Dy target. Bands formed by transfer of the 050221&_version=1&_userid=10&md5=e2d9a1df8c270d88913bf9b5192c1707"> proton can also be assigned. Two new Gallagher–Moszkowski splitting energies are reported. Although large peaks can be attributed to transfer of the 050221&_version=1&_userid=10&md5=2448d5e71096fbb1ac514ac0fac1f485"> and 050221&_version=1&_userid=10&md5=1a3c5458f682f7c52011f7b28b29e16e"> protons, strong Coriolis mixings of the four two-quasiparticle bands formed by these transfers in each nuclide, coupled with the unknown Gallagher–Moszkowski splittings and Newby shifts, limit the interpretation to some tentative assignments. From reaction Q-values the mass of ¹⁶²Tb is determined to be 80 keV higher than reported in the 2003 mass tables.
