Transverse quadrupole wake fields exist whenever the beam is not round, and therefore in an alternating gradient focusing system these fields cannot be eliminated. As a result, these fields represent a potential limitation on high intensity linac performance. In this note we calculate the magnitude of quadrupole wake field effects for the SLAC linac.

High level ab initio methods have been used to calculate values of the quadrupole moment of the ground X (1)Sigmag+ state of N2 on a dense radial mesh spanning the interval of 0.8-12.1 a.u. Detailed convergence tests indicate that the resulting equilibrium values of the quadrupole moment Theta(e)=-1.1273 a.u. and its first radial derivative dTheta(R)/dR/e=0.9604 a.u. have absolute uncertainties...

Cluster multipole orderings composed of atomic high-rank moments are theoretically investigated with a 5d-electron compound Ca5Ir3O12 in mind. exhibits two hidden orders: One is an intermediate-temperature phase time-reversal symmetry and the other low-temperature without symmetry. By performing augmented analyses for d-orbital model under hexagonal point group D3h, we find that 120°-type order...

We investigate the interior Einstein’s equations in case of a static, axially symmetric, perfect fluid source. present particular line element that is specially suitable for investigation this type gravitational fields. Assuming deviation from spherically symmetry small, we linearize corresponding and field find several classes vacuum solutions. some approximate solutions by imposing appropriat...

In this brief review, an overview about recent efforts to simulate the spectroscopic signatures of chiral molecules is given with focus on real time propagation approaches solve time-dependent Schrödinger equation. particular simulation electric circular dichroism spectra and vibrational Raman optical activity discussed. comparison linear absorption spectra, where only response dipole moment ne...
