“…While 96Zr shows magic properties [2] in accordance with the spherical shell model, a strong deformation has been reported [-3, 4] for X~176 The energy levels of 98Zr have hitherto been studied through the 96Zr(t,p) reaction [-2, 5]. Additionally, a first excited 0 § state at 853keV was proposed [-6] from investigations of the conversion electrons which are emitted in the//-decays of unseparated fission products.…”

“…The value U=0 + is excluded as the Vtransitions into 0 § states are observed. The value of U=7-proposed in [2] for the 4450 keV state can only be understood if there are two levels near this energy. The U-values of the levels which are fed through the 2.0 s decay are restricted to 3-, 4-or 5-.…”

“…(r~ lg9/2) (v lgT//) according to the strong coupling rule [24]. The allowed fl-decay to the 0 + states of 9SZr is then probably of tho type vgT/z--.~g9/2 assuming that these levels have a (~ gg/z)2-admixture [2]. The 0.65 s level is most probably not the ground state of 9Sy as the 39th proton is in the 2pl/2 orbital in the lighter Y isotopes.…”

“…4.1). The energy levels which were determined by the 96Zr(t,p)9SZr reaction [2] and the conversion electron measurements [6,7] are given for comparison. There is good agreement with Reference 2 for the low lying states except for the levels at 853.0, 1435.9 and 2490.1 keV, which are not fed in that reaction.…”

A study of the//-decay of 98y and of the level scheme of 98Zr was undertaken by the use of the two recoil fission product separators JOSEF and LOHENGRIN. Two //-decay modes have been detected for 98y, the half-lives of which are 0.65_+ 0.05 s and 2.0_+ 0.2 s. The spins and parities of the two states which undergo//-decay are proposed to be 1 § and 4-, respectively, with the configurations (~ l g9/2)(v l g~/2) and (~2pl/2) (v lg7/2). The measured Qp-value is 7300• for the 0.65s decay. The level scheme of 98Zr was deduced from 7,7-coincidence data. Absolute 7-intensities were obtained from two independent measurements. The half-life of the first excited state of 98Zr at 853.0keV with spin and parity 0 § was determined through delayed 7,e--measurements to be 63 _+Tns. No indication of the coexistence of two different nuclear shapes of 98Zr was found.
