Abstract

The neutron detector with ³He-filled counters placed in the focal plane of the VASSILISSA separator is used for measuring the average number and determining the multiplicity distribution of prompt neutrons from the spontaneous fission of heavy short-lived isotopes. The test reaction ⁴⁸Ca + ²⁰⁶Pb = 2n+²⁵²No is used for tuning the separator settings and calibrating the detector system with the spontaneous fission of the ²⁵²No. The average neutron number per ²⁵²No spontaneous fission event is as large as ν̄ = 4.06 ± 0.12. The short-lived heavy isotope ²⁴⁴Fm, produced in the complete fusion reaction ⁴⁰Ar + ²⁰⁶Pb, is investigated. The average number of neutrons per spontaneous fission of ²⁴⁴Fm from the experimental data (ν̄ = 3.3 ± 0.3) is determined for the first time.
