The cross sections of the 12 C (π , π n) 11 C and 12 C (π + +, π + n + π 0 p) 11 C reactions and their ratios have been measured at E π = 100, 130, 150, 180, 210, 245 and 295 MeV. The cross-section ratio at 180 MeV is 1.57±0.05....
Quotients by conjugation action, cross-sections, singularities,and representation rings Answers to several Grothendieck's questions on the conjugating action of a semisimple algebraic group formulated in his letter of January 15, 1969 to J.-P... VL Popov 被引量: 0发表: 2009年 Subconvex bounds...
We report triply and doubly differential cross sections for single ionization of helium by C 6+ impact at the incident energy of 100 MeV/amu. The calculation is based on the Glauber approximation (GA) method. A comparison is made of the present calculation with the results of other theoretica...
Cross sections for excitation of sodium by impact of ${mathrm{H}}^{+}$, ${mathrm{H}}_{2}$${mathrm{}}^{+}$, ${mathrm{H}}_{3}$${mathrm{}}^{+}$, and ${mathrm{H}}^{mathrm{ensuremath{-}}}$ ions Apparent cross sections are reported for the excitation of Na atoms from ...
ja:math and ψ′ production cross sections are studied for several proton induced reactions and in S U collisions, in the NA38 experiment, by measuring the resonances' decays in the muon pair channel. Whereas in p-A interactions the ψ′/ J / ψ ratio remains constantin going from p-p ...
Total and partial cross sections of the $^{112}\\mathrm{Sn}(\\ensuremath{\\alpha},\\ensuremath{\\gamma})^{116}\\mathrm{Te}$ reaction measured via in-beam $... An extended database of experimental data is needed to address uncertainties of the nuclear-physics input parameters for Hause...
Using recent BABAR, CMD-3 and SND data, the sum of e + e → 3(π+π), 2(π+ππ0), \\(p\\bar p\\) , \\(n\\bar n\\) cross sections is obtained. Unlike e + e 3(π+π) and e + e → 2(π+ππ0) processes, no structures in total cross sect... A.,E.,Obr...
Absolute differential cross sections for the reaction p + p --> pi+ + d were measured at 491.9, 575.5, 641.6, 728.2 and 793.0 MeV. These measurements covered an angular range from 50° to 120° in c.m. except for the 491.9 MeV case, where the angular range was ~70°-~105° in ...
The proton capture cross-sections of the two most proton-rich, stable isotopes of cadmium have been measured for the first time in the energy range relevant to the astrophysical p-process between E-p = 2.4 and 4.7 MeV. The Cd-106( p,gamma) In-107 and Cd-108( p,gamma) In-109 cross...
Fe3O4-γFe2O3 intermediate films were investigated in terms of the microstructures which appeared in the crosssections of the films. The samples were prepared at the oxidation stage where the coercivity of the films rapidly increased. It was found that, in the intermediate films, there were ...
