The ejection of protons from nitrogen on bombardment with α-particles of short range
U sing the expansion-cham ber m ethod, n inety p ro ton tracks are obtained from 850 pho to graphs showing the d isintegration of nitrogen under bom bardm ent by slow a-particles. The num ber of disintegrations decreases as the energy of the a-particles is reduced, b u t the photographs show disintegrations occurring for energies less th an T7 MeV. The angular dis tr ibu tion is approxim ate...
متن کاملBayesian Analysis of Alpha-Particles and Protons Nanodosimetric Ionization Distributions
Radiobiological data suggest that track quality depends on the statistical properties of ionization events in a biologically significant site of nanometric size. Such statistical properties can be studied experimentally with a track-nanodosimetric counter based on single electron detection mounted on a beam line of the Tandem-Alpi INFN Legnaro National Laboratories particle accelerator complex ...
متن کاملThe nature of anisotropic particles with short - range interactions
Anisotropic particles are used widely to control the thermodynamic and rheological properties of pharmaceuticals, cosmetics, food products, composite materials, and cements. In particular, rod-like particle suspensions exhibit unique equilibrium and non-equilibrium states at low particle loadings due to large excluded volumes and orientation-dependent attractions. However, the coupled effects o...
متن کاملMolecular Dynamics for 400 Million Particles with Short-range Interactions
We report the design and performance of a computational molecular dynamics (MD) code for 400 million particles interacting through the standard pairwise 6-12 Lennard-Jones potential on a 1024-node Intel Paragon, a distributed-memory MIMD parallel computer. The initially recorded “particle-step time” was .4 microseconds. A new inter-node communication strategy ensures high parallel efficiency fo...
متن کاملResonance phenomena in the disintegration of fluorine by protons
The bombardment of fluorine with protons gives rise to a strong emission ofy-radiation of quantum energy about 6-0 x 106 eV. The excitation function for this process shows a series of sharp resonances for proton energies up to about 2 x 106eV (Hafstad, Heydenburg and Tuve 1936; Bernet, Herb and Parkinson 1938; Curran, Dee and Petrzilka 1938). If the y-rays are a ttri buted to a simple capture ...
