作者： ZHANG Zheng-Jie MA dong-ping Department of Phy.ics Chengdu University of Technology Chengdu 610059 China Department of Applied Phy.ics Sichuan University Chengdu 610065 China

By.means of an improved ligand-field theory. the ＂pure electronic＂ PS and the PS due to EPI of R line of MgO： V^2＋ have been calculated, respectively. The calculated results are in very.good agreement with the experimental data. The behaviors of the pure electronic PS of R line of MgO：V^2＋ and the PS of its R line due to EPI are different. It is the combined effect of them that gives rise to the total PS of R line, which has satisfactorily.explained the experimental results. The mixing-degree of ｜t2^2（^3T1）e^4T2〉 and ｜t2^3 ^2E〉 in the wavefunetion of R level and its variation with pressure have been calculated and analy.ed. The comparison between the feature of R-line PS of MgO：V^2＋ and that of MgO：Cr^3＋ has been made.

Mineral chemistry. geochemistry.and U-Pb SHRIMP zircon data of the y.ngxin monzonitic intrusive in the foreland of the Dabie orogen

引用

Science China Earth Sciences 2006年第7期49卷 684-695页

作者： XUE Huaimin dong Shuwen JIAN ping Institute of Geology Chinese Academy of Geological Sciences Beijing 100037 China Chinese Academy of Geological Sciences Beijing 100037 China Institute of Geology Chinese Academy of Geological Sciences Beijing 100037 China

The y.ngxin composite intrusive consists of three generations of plutons, among which 90% are the second generation intrusions. The second generation intrusion has U-Pb SHRIMP zircon age of 134±2 Ma, substantially.y.unger than the early.stage of the y.nshanian. Amphibole and biotite, major mafic minerals in the y.ngxin plutons, are rich in magnesium, suggesting a deep source of their parental magma, possibly.derived from the upper mantle. Whole rock geochemical data on these rocks show that they.have high Al2O3 (15.92%―16.38%), relatively.high alkali (Na2O+K2O = 6.95%―7.37%) and higher Na2O contents than K2O (Na2O/K2O = 1.47―1.94). They.also have high Sr con-tents (816―897 μg/g) are enriched in strong incompatible elements such as Rb, U, Th, K and LREE, but depleted in HREE and y. Strong fractionation of LREE from HREE as indicated by.high (La/y.)N ratios ranging from 17.83 to 20.86. Although with little difference, the whole characteristics of the y.ngxin intrusive body.are greatly.similar to the adakite, referring that the formation of the parental magma may.relate with the partial melting of the basalt underplating from the mantle after delamina-tion of the mountain root of the Dabie orogen. The body.has been uplifted about 5 km since cooling concretion, the average rate was only.about 0.04 mm/a,much slower than that of the Dabie orogen in late Mesozoic, but the rates of denudation in two area are similar in Cenozoic.

Communications in Theoretical Phy.ics 2006年第4期45卷 754-760页

作者： ZHANG Zheng-Jie MA dong-ping College of Information Engineering Chengdu University of Technology Chengdu 610059 China Department of Applied Phy.ics Sichuan University Chengdu 610065 China

By.means of improved ligand-field theory. the ＂pure electronic＂ pressure-induced shifts （PS＇s） and the PS＇s due to electron-phonon interaction （EPI） of R1 line and R2 line of y.G：Cr^3＋ have been calculated, respectively. The calculated results are in very.good agreement with the experimental data. It is demonstrated that the admixture of │t^2 2（^3T1）e^4T2〉 and │t^3 2 ^2E〉 bases in the wavefunction of RI level of y.G：Crs＋ and its change with pressure play.a key.role for the PS of RI line. The behaviors of the ＂pure electronic＂ PS of RI line and the PS of RI line due to EPI are different. It is the combined eEect of them that gives rise to the total PS of R1 line, which has satisfactorily.explained the experimental results. The sy.tematic analy.es and comparisons between the feature of R1-line PS of y.G：Cr^3＋ and the ones of three laser cry.tals （GSGG：Cr^3＋, GGG：Cr^3＋ and ruby. have been made, and the origin of the difference between them has been revealed.

Pressure-Dependent Base-Wavefunction Admixture and Lifetime of R1 State of La3Lu2Ga3O12：Cr3＋

引用

Communications in Theoretical Phy.ics 2006年第6期45卷 1147-1152页

作者： ZHANG Zheng-Jie MA dong-ping College of Information Engineering Chengdu University of Technology Chengdu 610059 China Department of Applied Phy.ics Sichuan University Chengdu 610065 China

As a key.factor leading to the pressure-dependent R1-line-shift reversal and R1-state lifetime, at 10 K, the pressure-dependent variation of mixing-degree of ｜t2^2（^3T1）e^4T2） and ｜t2^32E〉 base-wavefunetions in the wavefunction of R1 state of LLGG：Cr^3＋ has been calculated and analy.ed. From this, the phy.ical origin of the pressure-dependent R1-line-shift reversal has been revealed. Furthermore, by.using the pressure-dependent values of the sum of all square mixlng-coefficients of ｜t2^2 （^3T1）e^4T2〉 in the wavefunction of R1 state, the lifetimes of R1 state of LLG G：Cr^3＋ at various pressures have been calculat, ed, which arc in good agreement with observed results. The quantum anticrossing effect between t2^32E and t2^2 （^3T1）e^4T2 levels due to both spin-orbital interaction and electron-phonon interaction is remarkable, which is related to the admixture of ｜t2^2（^3T1）e^4T2） and ｜t2^32E〉 as well as the low high cry.tal-field transition.

Energy.Spectrum, g Factors, Strain-Induced Level-Splittings and R-Line Thermal Shift of MgO:V^(2+)

引用

Communications in Theoretical Phy.ics 2008年第8期50卷 511-516页

作者： ZHANG Zheng-Jie MA dong-ping Department of Phy.ics Chengdu University of Technology Chengdu 610059 China Department of Applied Phy.ics Sichuan University Chengdu 610065 China

Traditional ligand-field theory.has to be improved by.taking into account both pure electronic contribution and electron-phonon interaction one （including lattice-vibrational relaxation energy.. By.means of improved ligand-field theory. the R line, t^322T1 and t^322T2 lines, t^22（^3T1）e^4T2, t^22（^3T1）e^4T1 and t2e^2（^4A2）4T1 bands, g factors of t^32 ^4A2 and t32E, four strain-induced level-splittings and R-line thermal shift of MgO：V^2＋ have been calculated. The results are in very.good agreement with the experimental data. It is found that for MgO：V^2＋, the contributions due to electronphonon interaction （EPI） come from the first-order term; the contributions from the second-order and higher terms are insignificant. In thermal shift of R line of MgO：V^2＋, the temperature-dependent contribution due to EPI is dominant. The results obtained in this work may.be used in theoretical calculations of other effects of EPI.
