Krypton-krypton molecular interaction
Physica, 1961Abstract Mainly on the basis of the various crystal properties the potential energy of interaction of krypton on a six-parameter model has been obtained. The potential energy curve thus obtained is more logical than those on the usual two or three parameter models (e.g. exp-6, L-J (6–12) etc.). It has been found that the force constants on the L-J

* BACKGROUND AND OBJECTIVES: Traditionally, the argon laser has been used with suture lysis. The authors evaluate the krypton laser and define the parameters for the successful use of the laser with this procedure. * PATIENTS AND METHODS: Five consecutive patients undergoing combined cataract and trabeculectomy surgery who were considered ...

Light absorption techniques are used to study the temporal dependence of the number densities of the 5s′00 and 5s12 krypton metastable atoms during the decay period (afterglow) of a pulsed discharge in krypton and krypton–nitrogen mixtures. The sensitivity of the temporal properties of the 5s′00 state of krypton to discharge pulse conditions was ...

Experiments demonstrating the feasibility of Kr-edge MAD on frozen crystals as a routine method for structure determination are reported. Approximately 50% of protein crystals can be successfully derivatized by pressurization with the noble gases xenon or krypton. While Xe has produced many useful derivatives for MIR phasing over the last several years,

Surface diffusion of metastable krypton atoms on krypton-doped solid argon
Journal of Luminescence, 1998Abstract Besides desorption and surface trapping of selectively excited Kr atoms at the surface of Kr-doped Ar crystals, a new relaxation mechanism has been observed. It includes surface diffusion of long-living atomic-type surface centers and guest-molecule formation at the surface.

Krypton red (647.1 nm) or krypton yellow (568.2 nm) laser trabeculoplasty was performed in 15 phakic eyes of 14 patients. After an average follow-up of five months, these patients had an average drop of intraocular pressure of 8.9 mm Hg. In addition, in eight of these patients studied, argon laser trabeculoplasty was performed in the opposite eye ...

Scattering of High Velocity Neutral Particles. VI. Krypton-Krypton
The Journal of Chemical Physics, 1955Total collision cross sections have been measured for krypton atoms with energies between 700 and 2100 ev, scattered in room temperature krypton, to obtain potential energy information for the interaction of two krypton atoms. The potential function may be represented by V(r)=2.55×10−10/r5.42 ergsfor r between 2.42 A and 3.14 A.

The coefficients of viscosity and thermal conductivity of binary mixtures of krypton with argon, neon and helium have been determined over the full range of composition of each mixture at a pressure of 70 cm of mercury and at a temperature in the range 18.0 to 18.3°C.
