    Notes: Abstract 32S and12C induced compound reactions on Fe, Ni and Se targets have been used to produce neutron deficient nuclei in the mass region 84≦A ≦87. In-beamγ-ray spectroscopy consisting of the measurement of excitation functions,γγ coincidences andγ-ray angular distributions has been performed. The following level energies and spin-parity values have been deduced:84Zr: 540 keV, 2+; 1262.8, (4+); 2137.2, (6+); 3089.286Zr: 751.9, 2+; 1666.6, (4+); 2670.0, (6+); 2705.5, (5); 3271.3; 3298.5, (8+); 3423.5, (7); 3531.5, (10+); 3645.9; 4326.1; 4417.3 Half-lives and energies ofγ-rays from the residual activities have been measured. The existence of three new isotopes could be established by their radioactive decay:84Nb(12±3 s)→84Zr86Nb(80±12 s)→86Zr87Mo(14.6±1.5 s)→87Nb→87Zr

    Observation of new nuclides37Si,40P,41S,42S produced in deeply inelastic reactions induced by40Ar on238U (1979)

    Notes: Abstract Atomic numbers and masses have been identified for the fragments 10≦Z≦18 and 20≦A≦45 produced in the reaction40Ar(263MeV)+238U. Four new neutron-rich nuclides,37Si,40P,41–42S have been observed as a result of deep inelastic collisions. The nuclide identification combined two independant time of flight measurements as well as two (Δ E×E) informations and was quite unambiguous.

    Rotational bands in77Kr (1975)
    Springer
    The European physical journal 275 (1975), S. 33-43

    Notes: Abstract Collective bands in77Kr have been studied with the help ofγ singles spectra,γγ coincidences,γ ray angular distributions and recoil-distance life time experiments measured during the irradiation of63Cu and64Ni targets with16O ions. Positive and negative parity bands with the following level energies, spins, and parities have been found: g.s. 5/2+; 150.1 keV 7/2+; 279.1 9/2+; 784.8 11/2+; 1003.7 13/2+; 1660.5 15/2+; 1919.1 (17/2+); 66.5 keV (3/2)−; 245.3 (5/2)−; 499.6 (7/2)−; 799.5 (9/2)−; 1177.3 (11/2)−; 1569.9 (13/2)−; 2063.2 (15/2)−. A mean life time of 170±17 nsec for the 66.5 keV state was measured withγγt coincidences and a mean life time of 48±13 psec for the 245.3 keV state was obtained with a recoildistance Doppler shift measurement.
