Measurement of the π0 multiplicity cross sections are reported for n0 ? 6, where n0 is the number of produced π0 particles, and for N ? 8, where N is the number of charged particles. The inclusive π0 cross section is 29 ± 3 mb. Values for the correlation parameters, 〈n0〉 and 〈n0(n0 ? 1)〉2, are also presented. 相似文献

In this paper, a man-machine interactive method is presented as an aid in solving the bicriterion mathematical programming problem. It is assumed that the two objective functions are real-valued functions of the decision variables which are themselves constrained to some compact and nonempty set. The overall utility function is assumed to be unknown explicitly to the decision-maker but is assumed to be a real-valued function defined on the pairs of feasible values of the objective functions and monotone non-decreasing in each argument. The decision-maker is required only to provide yes or no answers to questions regarding the desirability of increase or decrease in objective function values of solutions that he will not accept as optimal. Convergence of the method is indicated and a numerical example is presented in order to demonstrate its applicability. 相似文献

The solid-state behavior of MBBA has been studied by the technique of positron lifetime measurements. The positron data support
the exitence of at least two metastable forms of MBBA, one of which may be glassy. 相似文献

Oxygen uptake of 3 low molecular weight ethylene-propylene terpolymers (EPDM) and their respective bicyclic diolefin termonomers (dicyclopentadiene, ethylidene norbornene and methyl endomethylene hexahydronaphthalene) has been measured at ? 70°. 相似文献

Carbontetrachloride has been widely used in liquid phase μ SR as a calibrant of the asymmetry in view of its supposed 100%
diamagnetic muon yield. However, in the present letter, evidences are presented to show that this conventional use of CCl4 might be wrong and that there exists thermalized muonium in it that partially leads to a lost polarization. 相似文献

Direct reflectance, thermoreflectance, and electroreflectance have been measured for MnO, CoO, and NiO above the fundamental edge. Spectra of all three materials support a model containing both localized and one-electron band states. In MnO peaks with temperature coefficients of ~ 10?3 eV/K were observed at 5.7 and 6.9 eV, temperature-independent structure occurred at 5.4, 6.3, and 7.2 eV, and spectral features with indeterminate temperature dependence were seen at 4.6 and 5.5 eV. The temperature-dependent structure was assigned to one-electron interband transitions associated with anion 2p and cation 4s states; the temperature independent structure was assigned to crystal field split localized interionic transitions between the 3d-states of neighboring Mn ions. Thermoreflectance spectra for CoO exhibited temperature dependent structure (9.5 × × 10?4 eV/K at 5.0, 6.0, and 7.2 eV. A strong, temperature dependent electroreflectance oscillation was seen in NiO near 6.2 eV. On the basis of these data the interband gap between the anion 2p and cation 4s bands was determined to be 5.7 eV in MnO, 6.0 eV in CoO, and 6.2 eV in NiO. 相似文献
