Population distributions in the vibrational deactivation of benzene and benzene-d6. First and second moments derived from two-color infrared fluorescence measurements
(Elsevier, 1993-09-01)
Time-resolved two-color infrared fluorescence (IRF) from highly vibrationally excited benzene and benzene-d6 has been used to determine means and variances of the excited molecule population distributions over the majority ...
Elementary solutions of the transport equation and their applications
(Elsevier, 1960-01)
A new method of treating problems involving the transport equation is discussed. Starting from Van Kampen's observation that it is sufficient that "solutions" be distributions, the elementary solutions of the homogeneous ...
Euclidean Fermi fields with a hermitean Feynman-Kac-Nelson formula. I
(Springer-Verlag, 1974-03)
We construct free, Euclidean, spin one-half, quantum fields with the following properties: (i) CAR; (ii) Symanzik positivity; (iii) Osterwalder-Schrader positivity; (iv) no doubling of particle or spin states. They admit ...
An Auxiliary RF Channel with Convenient Phase Control for NMR Spectrometers
(Elsevier, 1993-09)
Absence of goldstino decoupling in hierarchical superunified models
(Elsevier, 1983-08-25)
It is shown that there exist a class of hierarchical supersymmetric unified models in which the Goldstino field does not decouple from that light states. We illustrate this with an SUN model. The phenomenology and cosmology ...
Measurement of sonic velocity in liquid Refrigerant 12
(The American Institute of Physics, 1977-08)
The sonic velocity in subcooled liquid Refrigerant 12 (CCl2F2) was measured at 26.7 °C using an apparatus designed to investigate transients associated with pipe blowdown. The mean value for sonic velocity obtained from ...
Efficient algorithms for estimating the width of nearly normal distributions
(Elsevier, 1983-06-15)
Typical physics data samples often conform to Gaussian distributions with admixtures of more slowly varying backgrounds. Under such circumstances the standard deviation is known to be a poor statistical measure of distribution ...
Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...
