Coalescing binary neutron stars (NS) are expected to be an important source of gravitational waves (GW) detectable by laser interferometers. We present here a simple method for determining the compactness ratio M/R of NS based on the observed deviation of the GW energy spectrum from point-mass behavior at the end of inspiral. Our method is based on the properties of quasiequilibrium binary NS s...

The 12A00 2 XA 0 1 electronic transition of the B3 molecule with origin band at 5990 cm 1 has been observed in a 6 K neon matrix. A vibrational progression in the spectrum corresponds to the excitation of the m1ða1Þ vibrational mode in the 1 A 00 2 state with a frequency of 1092 cm . The band system was detected after laser ablation of a boron rod and the origin band also after mass-selected de...

Previous results for the shift of the ionisation potential of an atom in a laser field are used to investigate the kinematics of multiphoton ionisation in either a laser beam or a laser pulse. Previous results for a laser beam show essentially no shifts of the 'above-threshold ionisation' peaks in the electron energy distribution and only small widths. Results for a laser pulse show the possibi...
