Sticky elastic collisions

Sticky elastic collisions.

The effects of purely elastic collisions on the dynamics of heavy inertial particles are investigated in a three-dimensional random incompressible flow. It is shown that the statistical properties of interparticle separations and relative velocities are strongly influenced by the occurrence of sticky elastic collisions-particle pairs undergo a large number of collisions against each other durin...

Elastic e-NO collisions.

In this paper we use the Schwinger multichannel method ~SMC! to calculate several types of cross sections related to the elastic electron scattering by NO. We show through the NO system that the elastic scattering of an electron by an open shell molecule is a much richer process than the corresponding scattering by closed shell targets. We present cross sections for unpolarized electron scatter...

Persistence of velocity following elastic collisions

2014 Elastic Kr*-He collisions have been studied using a two laser saturated-absorption experiment on the 03BB = 557 nm line of KrI. With the pump laser detuned from the atomic resonance, one can follow the collisional relaxation of Kr* atoms from a non-thermal distribution centred at vz ~ 0 back towards a thermal distribution.

Relative-Periodic Elastic Collisions of Water Waves

We compute time-periodic and relative-periodic solutions of the free-surface Euler equations that take the form of overtaking collisions of unidirectional solitary waves of different amplitude on a periodic domain. As a starting guess, we superpose two Stokes waves offset by half the spatial period. Using an overdetermined shooting method, the background radiation generated by collisions of the...
