“…Theoretical calculations by Ball 24 predict a low-lying f + state at 0.57 MeV and also predict a f~ state at 0.73 MeV and a f~ state at 0.90 MeV. Similar calculations have been reported by Vervier 2. The f~ predictions are in good agreement with the observed f~ level at 0Angular distributions for 94 Zr (rf, 3 He) 93 Y.…”

An investigation of the proton ground-state configurations in the even zirconium isotopes (A = 90, 92, 94, 96) was undertaken using the (d, 3 He) reaction at a deuteron energy of 34.4 MeV. The experimental angular distributions were compared with distorted-wave calculations in the finite-range approximation which include nonlocality in the distorted waves. The residual yttrium isotopes (A =89, 91, 93, 95) have £~* ground states, and the observed spectra can be interpreted in terms of a simple shell-model picture which considers hole and particle configurations in the lg 9 /2, 2pi/2, 2p 3/2 , and l/ 5 / 2 proton shells and allowed couplings in the 2^5/2 neutron shell. It was found that the filling of the 2d 5 /2 neutron shell apparently has a measurable effect on the relative amounts of the (2^i /2 ) 2 and (lgg/ 2 ) 2 proton admixtures in the zirconium ground states. The strength of the (2^i/ 2 ) 2 term in the ground-state wave functions was determined to be: 64% for 90 Zr, 55% for 92 Zr, 66% for ^Zr, and 86% for 96 Zr.

The Decay of 94SrThe nuclide 94Sr was isolated by chemical separation methods after thermal neutron induced fission of 2asU. Its decay properties were investigated employing semi-conductor spectrometers and coincidence techniques. A half-life of 74.1 + 0.3 sec was found. Besides the 1428.3 keV 7-ray we found 4 new y-rays which could be placed in a decay scheme comprising three excited states of 94y. The 1 + states in the u u-nuclides 90, 92, 94y and ss, 90, 92Rb are compared.
