The leading questions in today neutrino physics concern the transformation properties of neutrinos under charge conjugation, the lepton number conservation hypothesis and the values of neutrino masses. The answers can be obtained if the neutrinoless

The nuclear way to discover Majorana neutrinos is the neutrinoless ββ decay. An alternative is offered by the inverse process, neutrinoless radiative double electron capture accompanied by a photon emission. Two different mechanisms seem plausible:

Interactions of 150 MeV/amu 3 He ++ projectiles with solid gold targets have been studied at the isochronous cyclotron of the RCNP in Osaka. The 3 He + ions resulting from capture of the target electrons to the projectile were observed with the use o

The high-resolution spectra of thorium Mα 1,2 (M 5 N 6,7 ) and Mβ(M 4 N 6 ) X-ray lines induced by O and Ne ions with energies 376 and 178 MeV, respectively, have been measured using a von Hamos crystal spectrometer. The measured spectra exhibit th

The rapid progress in acceleration techniques, notably those of accelerating ions of any desired charge to relativistic energies and of storing them in cooling rings, has brought within the experimental reach a number of atomic processes at high (rel

The Kβ spectrum of 42Mo bombarded by 20.8 MeV/amu carbon ions was measured with high-resolution using a transmission-type bent crystal spectrometer operated in the modified DuMond slit geometry. The M-shell satellites of the Kβ2 transition could be
