High - Spin - State Spectroscopy with the Reaction ggsr ( pp , t , m ) g 9 Zr
نویسنده
چکیده
The pronounced selectivity of near-threshold (p, 7r ) reactions for high-spin two-particle, one-hole states is exploited, in the first spectroscopic application of a (p, n ) reaction, to identify previously unknown 25/2+ and 21/2+ (g9/2)' states in s9Zr. Relative cross sections for the two transitions are well reproduced by simple model calculations. The analyzing power for the 25/2+ state is markedly similar to previous (p„~, vr ) results for two-particle, onehole stretched states in lighter nuclei.

High - Spin Isomers in 9 ' Nb and 9 ' Zr via 5 Li - Induced Reactions
High spin levels in 'Nb and 'Zr have been studied with the reactions Sr{GI,i, 3n) ~ Nb and 8 Sr(GLi, P2n) 'Zr by pulsed-beam-p, p-p, and p-W(&) measurements. Isomers were found which agree with theoretical predictions: a v =5.42 + 0.18-p, sec state at 2035 keV in Nb, l(g&g2) pqg2, $ ), and a v=6.15+0.50-psec state at (8188) keV in 'Zr, [(g9~2) &&d5y2, ~~+).

متن کاملInfluence of Operational Parameters and Kinetic Modelling of Catalytic Wet Air Oxidation of Phenol by Al/Zr Pillared Clay Catalyst
Single and mixed oxide Al/Zr-pillared clay (Al/Zr-PILC) catalysts were synthesized and tested for catalytic wet air oxidation (CWAO) of aqueous phenol solution under milder conditions, in a semi-batch reactor. The catalysts were synthesized from natural bentonite clay using ultrasonic treatment during the aging and intercalation steps and were characterized <...
متن کاملSpin-dynamics of the spin-correlated radical pair in photosystem I. Pulsed time-resolved EPR at high magnetic field.
Spin-dynamics of the spin-correlated radical pair (SCRP) P(700)(+)A(1A)(-) in the photosystem I (PSI) reaction center protein have been investigated with high-frequency (HF), time-resolved EPR spectroscopy. The superior spectral resolution of HF EPR enables spin-dynamics for both the donor and acceptor radicals in the pair to be monitored independently. Decay constants of each spin were measure...
متن کاملZhang-Rice physics and anomalous copper states in A-site ordered perovskites
In low dimensional cuprates several interesting phenomena, including high Tc superconductivity, are deeply connected to electron correlations on Cu and the presence of the Zhang-Rice (ZR) singlet state. Here, we report on direct spectroscopic observation of the ZR state responsible for the low-energy physical properties in two isostructural A-site ordered cuprate perovskites, CaCu(3)Co(4)O(12) ...
متن کاملCalculations of Compound Nucleus Spin-parity Distributions Populated via the (p,t) Reaction in Support of Surrogate Reaction Measurements
The (p,t) transfer reaction is being studied for its potential use in surrogate reaction analyses. A theoretical model has been developed to predict spin-parity distributions of final states excited in the reaction. The model, after comparisons with experimental data, may provide a predictive capability to identify candidate isotopes for measurement. Preliminary results are presented for the Zr...
