By tracki.g the decay products i.-fli.ht wi.h si.i.on mi.ro-stri. detectors, the 2p decays of ^(30)Ar were observed for the fi.st ti.e. For the cali.rati.n purpose, 2p decays of ^(19)Mg were also remeasured by tracki.g the coi.ci.ent ^(17)Ne+p+p trajectori.s. By compari.g the measured angular p-17 Ne correlati.ns wi.h those obtai.ed from the correspondi.g Monte Carlo si.ulati.ns,the si.ultaneous 2p decay of ^(19)Mg ground state and the sequenti.l 2p emi.si.n of several known exci.ed states of ^(19)Mg were confi.med.

Si.pler formulas are deri.ed for one-range addi.i.n theorems for the i.teger and noni.teger n generali.ed ex- ponenti.l type orbi.als, momentum space orbi.als, and hyperspheri.al harmoni.s wi.h hyperboli. cosi.e （GETO HC, GMSO HC, and GHSH HC） i. posi.i.n, momentum and four-di.ensi.nal spaces, respecti.ely. The fi.al results are expressed i. terms of one-range addi.i.n theorems of complete orthonormal sets of Ca-exponenti.l type orbi.als, Ca- momentum space orbi.als and za-hyperspheri.al harmoni.s. We noti.e that the one-range addi.i.n theorems for i.teger and noni.teger n-Slater type orbi.als and Gaussi.n type orbi.als i. posi.i.n, momentum and four di.ensi.nal spaces are speci.l cases of GETO HC, GMSO HC, and GHSH HC. The theorems presented can be useful i. the accurate study of the electroni. structure of atomi. and molecular systems.

作者： i. i. Gusei.ov Department of Physi.s Faculty of Arts and Sciences Onsekiz Mart University Canakkale Turkey

The expansi.n formulas i. terms of complete orthonormal sets of ψ^α -exponenti.l type orbi.als are establi.hed for the Slater type orbi.als and Coulomb-Yukawa-li.e correlated i.teracti.n potenti.ls of i.teger and noni.teger i.di.es. These relati.ns are used i. obtai.i.g thei. unsymmetri.al and symmetri.al one-range addi.i.n theorems. The fi.al results are especi.lly useful i. the calculati.ns of multi.entre multi.lectron i.tegrals occurri.g when Hartree-Fock-Roothaan and expli.i.ly correlated methods are employed.

Mn2V2O7 thi. fi.ms were deposi.ed onto amorphous glass substrates usi.g a chemi.al bath deposi.i.n method and di.ferent deposi.i.n ti.e. X-ray di.fracti.n （XRD） analysi. was used to defi.e the structure of the fi.ms. Thei. roughness, thi.kness, and surface properti.s were evaluated through atomi. force mi.roscopy （AFM）. The hardness of the fi.ms was measured usi.g a nanohardness tester The fi.m thi.kness, average grai. si.e, and roughness were posi.i.ely correlated wi.h each other. These three parameters were observed to i.crease wi.h the deposi.i.n ti.e. The fi.m thi.kness and average grai. si.e were i.versely correlated wi.h the hardness and rough- ness. i. addi.i.n, the number of crystalli.es per uni. area and the di.locati.n densi.y were observed to be posi.i.ely correlated wi.h the hardness and roughness. Thi. study was desi.ned to eluci.ate and formali.e the underlyi.g reasons for these relati.nshi.s.

The model exhi.i.s many i.teresti.g cosmologi.al features. i.flati.n proceeds du to the presence of bulk vi.cosi.y and dark energy wi.hout requi.i.g the equati.n of state p =-p. Duri.g the i.flati.nary era the energy densi.y p does not remai. constant, as i. the de-Si.ter type. Moreover, the cosmologi.al and gravi.ati.nal constants i.crease exponenti.lly wi.h ti.e, whereas the energy densi.y and vi.cosi.y decrease exponenti.lly wi.h ti.e. The rate of mass creati.n duri.g i.flati.n i. found to be very huge suggesti.g that all matter i. the uni.erse i. created duri.g i.flati.n.

We i.vesti.ate a cosmologi.al model of a phantom energy wi.h a vari.ble cosmologi.al constant （∧） dependi.g on the energy densi.y （ρ） as ∧∝ρ^α,α=const and a vari.ble gravi.ati.nal constant G. The model requi.es α 〈 0 and a negati.e gravi.ati.nal constant. The cosmologi.al constant evolves wi.h ti.e as ∧ ∝ t^-2. For ω 〉 - 1 and α 〈 -1 the cosmologi.al constant ∧ 〈 0, G 〉 0 and ρ decrease wi.h cosmi. expansi.n. For ordi.ary energy （or dark energy）, i.e.ω 〉 -1, we have -1 〈 α〈 0 and β 〉 0 so that G〉0 i.creases wi.h ti.e and p decreases wi.h ti.e. Cosmi. accelerati.n wi.h dust parti.les i. granted, provi.ed -2/3 〈α〈 0 and ∧〉0.

Chi.ese Physi.s C 2009年第12期33卷 1340-1344页

作者： i. Jaeglé Departmement of Physi.s University of Basel CH-4056 Basel Switzerland

Photoproducti.n of mesons off the deuteron has been i.vesti.ated at a tagged photon beam of the Bonn ELSA accelerator wi.h the combi.ed Crystal Barrel - TAPS electromagneti. calori.eter for i.ci.ent photon energi.s up to 2.5 GeV. The mesons have been detected i. coi.ci.ence wi.h recoi. protons, neutrons and deuterons. Thi. allow the measurement of meson producti.n reacti.ns off the quasi.ree nucleons bound i. the deutron, as well as the coherent producti.n off the deuteron. The compari.on of quasi.ree proton reacti.ns to free proton reacti.ns can confi.m or i.vali.ate possi.le nuclear effects on the extracted cross secti.n reacti.ns. Furthermore the i.ospi. composi.i.n of a resonance can be esti.ated from the compari.on of quasi.ree proton and neutron reacti.ns. The quasi.ree photoproducti.n of the η＇ and π°η mesons off nucleons and the coherent photoproducti.n of π°η--pai.s off the deuteron are di.cussed.
