Phosphorescence produced by Canal Rays

Cosmic Rays produced by CDM-related mechanisms

We briefly review current theoretical and experimental status of Ultra-High Energy Cosmic Rays. We show that “top-down” mechanisms of UHE CR which involve heavy relic particle-like objects predict Galactic anisotropy of highest energy cosmic rays at the level of minimum ∼ 20%. This anisotropy is large enough to be either observed or ruled out in the next generation of experiments. This talk is ...

Chiral discrimination by phosphorescence

Mev X rays and photoneutrons from femtosecond laser-produced plasmas.

We demonstrate a novel method to monitor the total angular distribution of the spectrum of hard x-ray emission from a plasma generated with femtosecond laser pulses with an intensity of 5 x 10(18) W/cm2 on a solid target. Measured and calculated angular distributions of x rays show a pronounced anisotropy for MeV photon energies. We complemented the spectral information by demonstrating a (gamm...

Radicals Produced in Single Crystals of Thymine Derivatives by UV and X-Rays

Single crystals o f anhydrous thymine (T), thymine monohydrate (T ■ H 20 ) , 5,6-dihydrothymine (TH 2), 1-methylthymine (mT) and thymidine (dT) were irradiated with X-rays and UV between 77 K and 300 K. Six types o f radicals were analyzed by ESR-spectroscopy at 9.5 GHz and 35 GHz after exposure to X-rays. The anion radical occurred only in T • H 20 at 77 K, the 4-yl radical only in TH 2 at 77 ...
