The Accelerator mass spectrometry (AMS) analysing method is described with applications for the detection of tritium leaks, detection of pollution and for research in the fusion experiments. The special requirements for an experiment of AMS with tritium are also presented. This paper concludes by showing the possibilities for each AMS facility to perform applications for detecting and preventing the environment pollution with tritium.

The life-time and the magnetic dipole moment of the 1+ isomeric state in116Sb have been measured by the TDPAD method. The state was populated in the reaction116Sn(p, n)116Sb atE p =15 MeV. The obtained results,μ(1+,116Sb)=+2.47(9) n.m. andT 1/2= 194(4) ns, support the pure single particle [πd 5/2*vd 3/2] configuration for the 1+ isomeric state.

Calculations of elastic, inelastic and total neutron cross sections as well as of (p, n) reaction cross sections in theA=90 mass region have been performed, using the statistical model of Hofmann, Richert, Tepel and Weidenmuller. The optical model parameters were obtained by Finckh et al. from the neutron decay of IAR in the91Zr(p, n)91 Nb reaction. The calculations are in very good agreement with the published experimental data. The optical model parameters proved to be satisfactory up to aboutEn=8.0 MeV. The present work might be relevant to the evaluation of neutron data for reactor technology.

Two short-lived isomeric states in118Sb have been investigated by the118Sn(p, n),118Sn(d, 2n) and115In(α, n) reactions. The TDPAD method on solid and liquid metallic targets was used to measure the electromagnetic moments of these states. The results of the experiments are: $$\begin{gathered} T_{1/2} = 13.4{\text{ }}(3){\text{ }}ns I^\pi = 3^ - {\text{ }}g = - 1.254(31){\text{ }}|Q| = 0.25{\text{ }}(5){\text{ }}b, \hfill \\ T_{1/2} = 22.8{\text{ }}(4){\text{ }}ns I^\pi = 7^ + {\text{ }}g = + 0.680(18){\text{ }}|Q| > 1.4{\text{ }}b. \hfill \\ \end{gathered}$$ Pure\([\pi 2d_{5/2} \otimes v1h_{1{\text{ }}1/2} ]_{3 - }\) and\([\pi 1g_{9/2}^{ - 1} \otimes v2d_{5/2}^{ - 1} ]_{7 + }\) configurations have been established for the two isomeric states. An experimental evidence concerning the participation of the 1g 9 2/−1 proton shell-model intruder excitation into the positive parity low-lying level structure of the odd-odd118Sb nucleus was obtained.

The level scheme of the neutron deficient isotope111Sb up to about 3.7 MeV is established from in-beam gamma-ray spectroscopy experiments. The identification of the reaction channel using cross bombardments:95Mo+19F (56–68 MeV),106Cd+7Li (20–30 MeV),102Pd+11B (45 MeV), charged partice-γ and neutron-γ coincidences is discussed.
