Since 1993, neutrino research has been conducted at the Baikal Deep Underwater Neutrino Telescope (BDUNT). The first part of NT-200, the detector NT-36 with 36 optical modules (OMs) at 3 short strings, was put into operation and took data up to March 1995. A 72-OMs array, NT-72, run in 1995–96. In 1996, it was replaced by the four-string array NT-96. Summed over 700 days effective life time, 320,000,000 muon events have been collected with NT-36, -72, -96. The first neutrino events have been selected. Since April 6, 1997, NT-144, a six-string array with 144 OMs, took data in Lake Baikal. NT-200 array is completed in April 1998. The Baikal Neutrino Telescope NT-200 is being deployed in Lake Baikal, 3.6 kilometers (2.2 mi) from shore at a depth of 1.1 kilometers (0.68 mi). It consists of 192 optical modules (OMs)

 “Multi-particle photonuclear reactions in heavy nuclei”

Autor V. Makarenko(Scobeltsyn Institute of Nuclear Physics, MSU, Moscow, Russia)

The probability of a compound residual hot hypernucleus formation at the end of pre-equilibrium phase of high energy photonuclear reactions is calculated with a time dependent Monte Carlo Multicollisional Cascade (MCMC) approach.

A New Light-Speed Anisotropy Experiment: Absolute Motion and Gravitational Waves Detected

Autor:Reginald T. Cahill Flinders University, Adelaide 5001, Australia

Data from a new experiment measuring the anisotropy of the one-way speed of EM waves in a coaxial cable, gives the speed of light as 300,000±400±20km/s in a measured direction RA=5.5±2 hrs, Dec=70±10!S, is shown to be in excellent agreement with the results from seven previous anisotropy experiments, particularly those of Miller (1925/26), and even those of Michelson and Morley (1887).

Photon stimulated ion desorption of condensed CO₂ at ~ 85 K studied by synchrotron radiation

Autorzy: Gunar V. S. Mota^I; Daniel E. Weibel^II; Geovane S. Araújo^I; Maria Luiza M. RoccoInstituto de Química, Universidade Federal do Rio de Janeiro,

Photon stimulated ion desorption (PSID) from condensed carbon dioxide has been studied for photon excitation energies ranging from 93 to 193 eV. PSID studies have been performed at the Brazilian synchrotron light source (LNLS), Campinas, during a multi-bunch operation mode of the storage ring. The results showed that after photon excitation several ions desorbed from the CO₂ films: C⁺, O⁺, CO⁺and O₂⁺.
