• The total absorption method using water bath is applied to the case of an almost monoenergetic anisotropic neutron stream from artificial accelerator, to be used for standardizing the strength of a <SUP>2</SUP>H(<I>d</I>, <I>n</I>)<SUP>3</SUP>He source.<BR>A detailed neutron balance equation is derived by taking into consideration certain correction terms to account for the finite water bath and associated equipment in the source. An experimental procedure for calibrating the thermal-flux-distribution and monitor neutron detectors is established to permit determination of the total loss of thermal neutrons in the bath and of the source strength at a given reference time. This calibration of the monitor detector makes it possible to measure the source strength as a function of time during accelerator operation simply by measuring only the counting rate registered by the detector.
