چکیده
Relativistic formulas for the electric quadrupole moment of a hydrogenlike atom, induced by the hyperfine interaction, are derived for ns and np1/2 states. Both the magnetic dipole and electric quadrupole hyperfine interactions are taken into account. The formulas are valid for ions with arbitrary nuclear charge and spin. The induced quadrupole moment is compared with the nuclear quadrupole moment for a wide range of hydrogenlike ions.

This work evaluates the model dependence of the electric and Coulomb quadrupole amplitudes (E2, C2) in the predominantly M1 (magnetic dipole-quark spin flip) γ * N → ∆ transition. Both the model-to-model dependence and the intrinsic model uncertainties are evaluated and found to be comparable to each other and no larger than the experimental errors. It is confirmed that the quadrupole amplitude...

In the interaction of two electric quadrupoles, there is at short range a contact term proportional to the second derivative of a delta function. This contact term contributes to the hyperfine splitting of bound states of two particles with spin one or higher-for example the bound state of Ω − and a nucleus with spin one. The contact hyperfine splitting occurs in states with orbital angular mom...

We present a review of BaBar results on e+e-annihilations into exclusive hadronic final states using the initial state radiation technique. Cross sections over the √ s range from threshold to 4.5 GeV, with very small point-to-point systematic errors, are presented for the 3π, 2(π + π −), 3(π + π −), 2(π + π −)2π 0 , K + K − π + π − , 2(K + K −) and p¯ p final states. The proton form factor and ...
