Description	First nuclear activation experiments have been carried out using the new accelerator for relativistic particles NUCLO-TRON in Dubna. The distribution of neutrons emitted during the irradiation with 0.65, 1.0 and 1.5 GeV protons from a lead target (circle divide = 8 cm, 1 = 20 cm) and moderated by surrounding paraffin of 6 cm thickness was studied with radiochemical sensors along the beam axis on top of the moderator Small La-139-sensors of approximately 1 g each were used to measure essentially the thermal neutron fluence at different depths near the surface: i.e. on top of the moderator, in 10 mm deep holes and in 20 mm deep holes, respectively. The reaction La-139 (n, gamma) La-140 (tau(1/2) = 40.27 h) was studied using standard procedures of gamma-ray spectrometry and data analysis. The induced activity of La-140 increases strongly with the depth of the hole inside the moderator Its activity distribution along the beam direction on top of the moderator has its maximum about 10 cm downstream the ent First nuclear activation experiments have been carried out using the new accelerator for relativistic particles NUCLO-TRON in Dubna.
