nuclear energy level transitionsnuclei with 6lesAles19/ A2320L Nuclear gamma transitions and level energiesRayleigh-Schrdinger perturbation theory through second order is applied to the problem of electromagnetic transitions in closed-shell-plus-one-nucleon nuclei. The concept of effective charge is ...
We consider the effect of higher twist operators of the Wilson operator product expansion in the structure function $F_{2}(x,Q^{2})$ at small-$x$, taking into account QCD effective charges whose infrared behavior is constrained by a dynamical mass scale. The higher twist corrections are ...
2. Thermodynamic Variables of Higher Curvature Charged AdS Black Holes The effective action in the Lovelock gravity in ( + 1) dimen- sions can be written as (here we have taken the gravitational constant = 1) [4] I = 1 16 [( +1)/2] ∫ +1 √− ∑ L , =0 (1) where is ...
[NH] have no detectable influence upon the formation of higher order chromatin structures, but they can prevent the unravelling of nucleosomes at very low ionic strength, presumably by charge shielding. For the appearance of zigzag-shaped fibres and for the condensation into compact fibres with ...
The study of higher-spin theories is motivated by both practical and theoretical questions. Massive higher-spin particles play a phenomenological role in describing composite states (such as those occurring in nuclear resonances of QCD) and are a crucial part of the spectrum of string theories. In...
Electrochemical characterization of NVPF samples in NVPF/Na half cells at a current of C/10 and cycled between 4.4 and 3.0 V. The first charge process alone is controlled by limiting the amount of Na+extracted (Δx = 2.0, 2.25, 2.50, 2.75, and 3.0).aVoltage-composition curves (...
bites were preanchored at the bottom of the trap, and FG-Nups formed a selective barrier above them. By detecting the molecules bound to the bites, they demonstrated the critical parameters of an effective diffusion barrier and how the nuclear transport receptor Ntf2 can selectively transport ...
11±/DCM charge-recombination rates decrease asTincreases affordingEa= –0.86 ± 0.10 kcal mol–1. This negative effective activation is assigned to the increase ofεfrom 9.0 at 293 K to 15.5 at 187 K, with the corresponding decrease in exothermicity from –74.0 to –71.4 kcal mol–1(Supple...
We calculate the charged hypermultiplet low-energy effective action in the Coulomb branch of the 4D, N = 2 gauge theory, by using the harmonic superspace a... E.A. Ivanov and S.V. Ketov and B.M. Zupnik - 《Nuclear Physics B》 被引量: 71发表: 1998年 Many-spin effects in inelastic...
