Deuteron beam current ~2.0 microA, 4174400100023 pressure of gaseous deuterium 2.5 atm. 4174400100024 SAMPLE . Natural NaCl and BaCl(2) placed in back-to-back 4174400100025 geometry. Chemical purity > 99.5 %. 4174400100026 Prepared by vacuum evaporation on tantalum backing of 4174400100027 0.1 mm thickness, 48 mm diameter. 4174400100028 Samples diameter 44 mm. 4174400100029 Thickness: 4174400100030 - NaCl : 707, 667, 302, and 289 microgram/cm2, 4174400100031 - BaCl(2) : 125 and 108 microgram/cm2. 4174400100032 .

Working gas Kr+ 3% ch(4) at4174400100037 0.6 atm pressure. 4174400100038 Alpha-particle detection efficiency was calculate by 4174400100039 Monte Carlo method to be 80-97 % depending on the 4174400100040 neutron energy, sample thickness and thresholds of 4174400100041 measurements. 4174400100042 . An alpha source ( 4.197 and 4.775 MeV) containing 4174400100043 the 234U and 238U isotopes was used for energy 4174400100044 calibration of the detection system. 4174400100045 . U-238 fission fragments detection efficiency ~97%. 4174400100046 (LONGC) He-3 long counter was also used as neutron flux4174400100047 monitor in all measurements.
