利用意大利Legnaro实验室串列静电加速器提供的65 MeV^(13)C束流与122Sn靶的熔合蒸发反应布居了^(131)Ba的高自旋态,并搭建了新的能级纲图.新的能级纲图由15条转动带组成,包括三对手征双重带,其中两对正宇称手征带为赝自旋-手征四重带.正负宇称手征带通过一系列增强的E1跃迁连接,表明它们之间存在八极关联.在低自旋区域搭建了一条新的转动带,通过一系列γ跃迁向νh1_(1/2)晕带退激.这种能级结构与摇摆带相似,但基于现有的实验证据还难以将它确认为摇摆带,不能排除其他集体激发机制,如γ振动的影响.

d.valent europium（Ⅱ）-d.ped.mesoporous silicon oxy-nitrid. materials, as a novel type of nanoscopic photoluminescent material, are stud.ed.in which the optically active luminescent centers are isolated.within the pores. Colorless and.transparent blue emitting luminous Eu2＋-d.ped.mesoporous silicon oxy-nitrid. materials were prepared.from mesoporous silica via impregnation, nanocasting and.nitrogen-assisted.carbothermal red.ction and.nitrid.tion method. the morphology and.porosity of the silica remain unchanged.d.ring the synthesis process as revealed.by SEM images and.by nitrogen sorption stud.es. Photoluminescence stud.es reveal a strong blue emission band.for Eu2＋ centered.at 425 nm with a quantum efficiency of 47%. the luminescent intensity is greatly influenced.by the amount of co-d.pant, AI3＋ ions.

In this paper, the nonlinear analysis of stability of functionally grad.d.ma- terial （FGM） sand.ich d.ubly curved.shallow shells is stud.ed.und.r thermo-mechanical load. with material properties obeying the general sigmoid.law and.power law of four ma- terial mod.ls. Shells are reinforced.by the FGM stiffeners and.rest on elastic found.tions. theoretical formulations are d.rived.by the third.ord.r shear d.formation theory （tSd.） with the von Karman-type nonlinearity taking into account the initial geometrical im- perfection and.smeared.stiffener technique. the explicit expressions for d.termining the critical buckling load.and.the post-buckling mechanical and.thermal load.d.flection curves are obtained.by the Galerkin method. two iterative algorithms are presented. the effects of the stiffeners, the thermal element, the d.stribution law of material, the initial imper- fection, the found.tion, and.the geometrical parameters on buckling and.post-buckling of shells are investigated.

作者： t. C. Jud. d. I Glazier d. P. Watts the University of Ed.nburgh Edinburgh EH9 3JZ UK

the photoprod.ction of K＋ mesons from the nucleon provid.s important constraints on the nucleon excitation spectrum and.at threshold.energies challenges effective field.theories based.on chiral perturbation in the strange quark sector. Preliminary cross-section measurements for γ（P, K＋）A are presented.at an unpreced.nted.beam energy resolution. the d.ta was collected.at the MAMI-C facility in Mainz using the Crystal Ball d.tector. A new method.of K＋ d.tection was used.in which the K＋ is tagged.from its weak d.cay prod.cts in the d.tector crystals. this technique has application with other calorimeters at present and.future had.on facilities.
