A066100100008 (4ZZZDUB) Laboratory of particle physics. A066100100009 REFERENCE (J,JP/G,26,1171,2000) A066100100010 REL-REF (R,,B.M.BOBCHENKO+,J,YF,30,1553,1979) The value of the A066100100011 inelastic cross section of the 12-C+P reaction was A066100100012 taken as 250 +/- 2 mb. A066100100013 COMMENT -By authors. In this case all the nuclei produced by A066100100014 beam fragmentation are emitted in a narrow cone along A066100100015 the beam direction and their momenta per nucleon are A066100100016 close to the projectile value. Therefore, it is A066100100017 possible to detect all the nuclei that are produced, A066100100018 including those with very small energy in the A066100100019 projectile reference frame. A066100100020 FACILITY (SYNCY,4ZZZDUB) Slow extraction beam VP-1 A066100100021 DETECTOR (SPEC) The ANOMALON magnetic spectrometer is based on aA066100100022 system of multiwire proportional chambers (MWPC) and anA066100100023 analysing magnet. It also includes a Cherenkov A066100100024 hodoscope for determining fragment charges, a trigger A066100100025 system consisting of scintillation and Cherenkov A066100100026 detectors, and a beam monitor. For the beam A066100100027 fragmentation cross section measurements the ANOMALON A066100100028 set-up was equipped with a liquid hydrogen target. A066100100029 MWPCs constitute a coordinate detector for determiningA066100100030 The positions of the charged-particle tracks. A066100100031 More detailed description see: A066100100032 1.

Yu.T.Borzunov et al., JINR Rapid Commun. 1/81 (1997)A066100100034 SAMPLE The target is 59 mm in diameter and 136 mm long A066100100035 (equivalent to 0.94 g/cm**2). The total thickness of A066100100036 the two mylar windows is 67 mg/cm**2.

A066100100041 CORRECTION The background correction factor has been calculated A066100100042 separately for each isotope using the results of A066100100043 measurements with an empty target and with hydrogen. A066100100044 ERR-ANALYS (ERR-S) Statistical error. A066100100045 (ERR-1) The systematic errors are due mainly to A066100100046 uncertainty regarding the efficiency of track A066100100047 reconstruction (varying with Z). Other Factors being A066100100048 negligible. A066100100049 (ERR-T) Total uncertainty.
