Using a shell model diagonalization which includes 2¯hω excitations the spinorbit splittings for mass numbers 5, 15 and 17 are studied. The contributions of the two-body spin-orbit and tensor interactions are studied separately and in combination. It is found that the second-order effects involving the twobody spin-orbit interaction are more important than the second-order tensor effects. For A = 5, the overall effect of the higher-shell admixtures is to decrease the p1/2 − p3/2 splitting, but for A = 15 this splitting is increased by a fair amount, and for A = 17 there is only a miniscule increase in the d3/2 − d5/2 splitting. These results are in qualitative agreement with data as well as perturbative analysis. I.

We study the perturbative dynamics of noncommutative field theories on Rd, and find an intriguing mixing of the UV and the IR. High energies of virtual particles in loops produce non-analyticity at low momentum. Consequently, the low energy effective action is singular at zero momentum even when

temperature was lowered.

We present observations of the energy spectra and timing of some of the largest solar particle events of solar cycle 23, including the events of October-November 2003 and the January 20, 2005 event, using data from ACE, SAMPEX, and GOES. These spectra are all well fit by a double power-law form

ABSTRACT. The utility of extracting CY particle power, and then diverting this power to fast fuel ions, is investigated. As power is diverted to fast ions and then to ions, a number of effects come into play, as the relative amounts of pressure taken up by electrons, fuel ions and fast CY particles

Until now, calculation of the rates of change of the damping partition numbers(‘~21 with particle energy took into account only the effects of quadrupole fieldst31. It has been foundt41, however, by tracking particles(5) in the LEP Elec-tron Positron Accumulato#l that the actual variation
