AUTHOR INDEX .......................................................................................................................... 151 SINS Annual Report 1995 3 FOREWORD The Institute for Nuclear Studies was founded on January 1,1983. It was previously a part of the former Institute of Nuclear Research which had been engaged in work on atomic physics since 1955. On October 10,1987 the Institute was named the Soltan Institute for Nuclear Studies (SINS) in memory of Professor Andrzej SOLTAN, a pioneer of nuclear science in Poland, who in 1958 (together with Leopold Infeld) also initiated plasma physics studies in Warsaw. According to its statutes, the Institute is involved in basic research like: nuclear physics, particle and high energy physics, cosmic ray physics, plasma physics as well as developmental work and implementations resulting from chosen trends in nuclear physics, nuclear electronics, accelerator technology, radiation detection, radiation transport, instrumentation and plasma physics technology. Many essential results have been obtained by the Institutes scientific staff in fundamental research. Among them the most worthy of mention are: the long halflife predicted theoretically for isotopes of the elements with proton number Z=110 and 111 and neutron number around N=162 by A.Sobiczewski group of the SINS (prize of the Polish Science Foundation); a new improved formula for the Coulomb corrections to Bose - Einstein correlations; importance of collective excitation in the description of multistep direct reactions; determination of nuclear friction in strongly damped reactions from precision neutron multiplicities; importance of multi-electron effects in the K plus M shell ionization by energetics projectiles and electron beam; soliton breakup in plasmas and other classical media; complex studies of the emission of X-ray, charged particle beams and neutrons from plasma-focus facilities; determination of the spin structure of the nucleon; the results obtained by the SINS Warsaw group in the DELPHI experiment at CERN, achievements in heavy quark physics, the spectroscopy of excited b - mesons B , B , B" ; Several constructions and development projects showed considerable progress during the year: pulse-shape discrimination for particle identification in "EuroSiB" - a 4ir Si-ball for charge particle detection; studies of the properties of the new LuAP:Ce scintillator the method and results obtained in modification of the surface properties of nitrogen- alloyed steells; dosimetry for radiotherapy and radiological protection; optimation of HRSi detectors technology for X-ray spectrometry design of the accelerating structure for 6-15 MeV medical accelerator. In our Experimental Establishment for Nuclear Equipment (ZDAJ) several construction and development projects showed considerable progress. Among them are: the therapeutical accelerator "Co-Line" 4 MeV, designed and constructed during 1993-1994. They have X-ray beam parameters close to Co-Unit beam parameters. Co-Line 4 SINS Annual Report 1995 accelerators have been working since December 1994 in the Regional Oncological Centre in Lodz, and since Dec. 1995 in Lublin Oncological Centre; the development and testing of a fully computerized system of medical accelerator parameter control and steering ("NEPTUN" and "Co-Line"); In spite of financial difficulties over the last years we were able to publish about 360 scientific papers during 1995, more than half
