A description is given of the experimental measurement of the prompt- neutron lifetlme parameter of a SPERT watermoderated and reflected reactor using the l/v-absorber pertarbation technique. The l/ beta /sub eff/ result given by the experiment is compared with the dynamic value obtained from super prompt- critical power excursion experiments performed on the same core. The latter value is found to be constant throughout the reciprocal reactor period range 0 < alpha < 300 sec/sup -1/; consequently, the comparison permits an evaluation of the static l/v-absorber method in terms of the direct step-transient technique.
