WEPSB20	Experimental Study of the Time Dependence of the Activity of Delayed Neutrons in the Fission of 235U by Neutrons from the Reaction 7Li(p, n) on the Electrostatic Accelerator EG-1	200
	K.V. Mitrofanov, A.S. Egorov, D.E. Gremyachkin, V.F. Mitrofanov, V.M. Piksaikin, B.F. Samylin IPPE, Obninsk, Russia
	In the present work the installation created on the basis of the accelerator EG-1 (IPPE) for the experimental studies of the time dependence of delayed neutron activity from neutron induced fission of 235U is described. Measurements were carried out with neutron beam generated with the help of the 7Li(p, n) reaction. The lower limit of the investigated time range was governed by the proton beam switching system that was 20 ms. It was shown that the temporary characteristics of delayed neutrons from the fission of 235U by epithermal neutrons is consistent with the time dependence which at present is recommended as a standard. In case of the fast neutron induced fission of 235U the measured decay curve of delayed neutrons shows excess of counting rate in the time interval 0.01-0.2 s as compared with the decay curve corresponding to the recommended data.

WEPSB21	Registration of Gamma Rays from the Reaction 16O(n, p)16N on the Direct Neutron Beam of Cascade Generator KG-2.5	203
	K.V. Mitrofanov, A.S. Egorov, V.M. Piksaikin, B.F. Samylin IPPE, Obninsk, Russia
	In the present work the results of analysis of the oxygen content in the water with the help of gamma-rays registration from the reaction 16O(n, p)16N is described. The samples were installed permanently on the direct beam of neutrons generated by the reaction 7Li(d, n) in the cascade generator KG-2.5 (IPPE). A comparison was carried out with experimental data obtained by the activation method in similar experimental conditions.

In the present work the results of analysis of the oxygen content in the water with the help of gamma-rays registration from the reaction 16O(n, p)16N is described. The samples were installed permanently on the direct beam of neutrons generated by the reaction 7Li(d, n) in the cascade generator KG-2.5 (IPPE). A comparison was carried out with experimental data obtained by the activation method in similar experimental conditions.
