Some opportunities of determination of nuclear states mean life

Two variants of experimental installations on the heavy ions and neutron beams which allow to widen the measurements opportunities of nuclear state lifetime are presented. First one assumes the use of the Y-150 isochronous cyclotron of the Institute of Nuclear Physics of National Nuclear Center of Republic of Kazakstan. It allows get the ion beams of nitrogen, oxygen and carbon with energy of the order of 5 eV/nucleon. The experimental facility created out in radial channel of WWR-K reactor has being used in second variant. It is design for non-elastic scattering of fast neutrons. The facility allows to measure the γ-radiation from reaction (n, n'γ) within angles range 51o-146o relatively to direction of falling neutron beam. This facility allows to measure nuclear state lifetime τ≤10-15 c. 17 refs
