[en] The lightest nuclei in the A = 130 mass region reachable with stable beams were investigated by using the ⁴⁰Ca+⁹²Mo fusion-evaporation reaction and the powerful detection system consisting of GASP+ISIS+n-ring at Legnaro (Italy). The level scheme of ¹²²La was established for the first time. The observed rotational bands are compared with the bands observed in the heavier Lanthanum nuclei and possible configuration assignments are discussed

[en] One of the most exciting subject in contemporary nuclear physics is the study of nuclei at the limit of stability with respect to particle emission. Recently, there has been an intensive experimental activity in measuring the proton decay and large variety of proton emitters were observed in the large variety of proton with 50 < z<82. . Very recently the proton radioactivity from ¹¹⁷La, ¹²¹Pr, ¹³¹Eu and ¹⁴¹Ho has been identified. The proton decay rates deviates significantly from calculations assuming spherical configurations, thus indicating the onset of large deformations in the drip line nuclei below Z=69. However, a detailed study of the structure of these nuclei can only be performed by means of ?-ray spectroscopy using large detector arrays coupled with efficient light charged particles detectors, since the cross section for their population with the presently available stable beams are very low

[en] A search for isomeric states was performed in the nucleus 60140Nd80 using in-beam γ-ray spectroscopy and the 126Te(18O,4n) reaction. Prompt and delayed γ-ray coincidences were measured with the AFRODITE spectrometer using the pulsed beam delivered by the Separated Sector Cyclotron of iThemba LABS. One new isomer was identified, with spin-parity Iπ=20+ and lifetime T1/2≥400 ns, at an excitation energy Ex=7430 keV. The lifetime of the 10+ isomer at Ex=3619 keV was determined to be 32.9(1.8) ns, confirming the previously reported value. The configuration of the Iπ=20+ isomer is assigned based on configuration-dependent cranked Nilsson-Strutinsky (CNS) calculations as a state π(d5/2g7/2)10+-4xν(h11/2-2)10+, with the spin vectors of the six holes in the 64146Gd82 core fully aligned

[en] Excited states in the very neutron-deficient ¹²²La nucleus have been established for the first time using the ⁹²Mo(⁴⁰Ca,2α1p1n) reaction at beam energies of 190 and 200 MeV. The observed transitions were grouped in three bands. Configurations have been assigned to the observed bands based on the properties extracted from the experimental data and on cranked shell model calculations. (orig.)

[en] The level structure of ₆₀¹⁴⁰Nd₈₀ has been established up to spin 48 by in-beam γ-ray spectroscopy by use of the ⁹⁶Zr(⁴⁸Ca, 4n) reaction. High-fold γ-ray coincidences were measured with the EUROBALL spectrometer. Twelve new rotational bands have been discovered at high spins. They are interpreted as being formed in a deep triaxial minimum at ε₂≅0.25 and γ≅35 deg. Possible configurations are assigned to the observed bands on the basis of configuration-dependent cranked Nilsson-Strutinsky calculations
