The odd-A Te isotopes, [sup 119–131]Te, have been investigated via (d,p), (pvector ,p), (dvector ,t), ([sup 3]He,α) and (n,γ) reactions. The application of polarized deuterons in the (d,p) and (d,t) reaction allowed us to construct essentially complete level schemes with spin and parities up to about 2÷3 MeV. On the other hand, the measurement of γ-γ coincidences in the (n,γ) reaction enable us to place most of the γ transitions in the decay schemes of the odd Te isotopes. The experimental systematics of both positive and negative parity low-lying states for the whole odd Te chain are reasonably well described with Interacting Boson-Fermion Model-1 with an essentially constant boson-fermion interaction. The combination of the neutron transfer reactions and (n,γ) reaction helps us to understand the origin of the anomalous population of the long-lived isomers in odd-A Te isotopes. The evidence for the direct process mechanism in [sup 127]Te, [sup 129]Te and [sup 131]Te was observed. © 2000 American Institute of Physics.

    Maraviroc labeled with hydrogen isotopes was prepared. Maraviroc molecules contain, on the average, more than four atoms of hydrogen isotopes. The isotope distribution was studied by mass spectrometry. If the amount of deuterium incorporated in Maraviroc molecule is taken as 100%, the triazole...
