Experimental investigation of high-energy photon splitting in atomic fields.

Data analysis of an experiment in which photon splitting in atomic fields was observed is presented. The experiment was performed at the tagged photon beam of the ROKK-1M facility at the VEPP-4M collider. In the energy region of 120-450 MeV, statistics of 1.6x10(9) photons incident on the BGO target was collected. About 400 candidate photon-splitting events were reconstructed. Within the attained experimental accuracy, the experimental results are consistent with the calculated exact atomic-field cross section. The predictions obtained in the Born approximation differ significantly from the experimental results.

[The analysis of the methylenedioxy derivatives of amphetamine].

Methods for analysis of narcotics belonging to amphetamine methylene dioxy derivatives (MDD) are reviewed. The characteristics of these agents, their metabolism, and methods used for their detection and identification (TLC, GC, HPLC, GC/MS) are described. Methods for their extraction from biological objects (human urine and hair) are described. Efficacy of MDMA and MDEA from the urine by different extractants is assessed. The data demonstrate different potentialities for detection and identification of amphetamine MDD, including those in biological specimens (human urine and hairs), by numerous chromatographic methods.

[Immunochemical methods in detection of opiates in tissues and organs].

Conditions of isolation of opiates from tissues and analysis of the resultant extracts by immunochemical methods are discussed. The main characteristics of OPIATES U kits (Pharmatech) for polarization fluorescent immunoanalysis of cadaveric material (liver) are determined. Immunochemical methods for forensic chemical analysis for opiates are experimentally compared.
