“…The ions were supposed to be accelerated to Lorentz factors γ ≥ 1000. The conclusion is that such measurement is possible, though it is difficult to conduct (in the subsequent literature on this subject, the interest shifted from monochromatic EC-beams to non-monochromatic β-beams, which could be made much more intense with the use of short-living isotopes; see, e.g., [24]).…”

A possibility to produce a modulated monochromatic neutrino beam is discussed. Monochromatic neutrinos can be obtained in electron capture by nuclei of atoms or ions, in particular, by nuclei of hydrogen-like ions. It is shown that monochromatic neutrino beam from such hydrogen-like ions with nuclei of non-zero spin can be modulated because of different probabilities of electron capture from hyperfine states. Modulation arises by means of inducing of electromagnetic transitions between the hyperfine states. Requirements for the hydrogen-like ions with necessary properties are discussed. A list of the appropriate nuclei for such ions is presented. *

“…The high-resolution measurements of the spectrum of low energy outgoing electrons need the detectors with the ultra low threshold and background. The interesting concepts of various (monochromatic) ν e sources are also worth noticing [94][95][96][97][98][99]. A preliminary study on the feasibility of electron polarized scintillating GSO target has been carried out by [34].…”

Neutrino elastic scattering on polarized electrons as a tool for probing the neutrino nature

Possibility of using the polarized electron target (PET) for testing the neutrino nature is considered. One assumes that the incoming electron neutrino (ν e ) beam is the superposition of left chiral states with right chiral ones. Consequently the non-vanishing transversal components of ν e spin polarization may appear, both T-even and T-odd. ν e s are produced by the low energy monochromatic (un)polarized emitter located at a near distance from the hypothetical detector which is able to measure both the azimuthal angle and polar angle of the recoil electrons, and/or also the energy of the outgoing electrons with a high resolution. A detection process is the elastic scattering of ν e s (Dirac or Majorana) on the polarized electrons. Left chiral (LC) ν e s interact mainly by the standard V − A interaction, while right chiral (RC) ones participate only in the non-standard V + A, scalar S R , pseudoscalar P R and tensor T R interactions. We show that a distinction between the Dirac and Majorana ν e s is possible both for the purely left chiral states and the left-right superposition. In the first case a departure from the standard prediction of the azimuthal asymmetry of recoil electrons is caused by the interferences between the non-standard complex S and T couplings, proportional to the angular correlations (T-even and T-odd) among the polarization of the electron target, the incoming neutrino momentum and the outgoing electron momentum. Such a deviation would indicate the Dirac nature of ν e s. In the second variant the azimuthal asymmetry, polar distribution and energy spectrum of scattered electrons are sensitive to the interference terms between the standard and exotic interactions, proportional to the various angular correlations (T-even and T-odd) among the transversal ν e spin polarization (related to the ν e source), the electron target polarization, the incoming ν e momentum and the outgoing electron momentum. The basic difference a between the Dirac and Majorana ν e s arises from the absence of T and V interactions in the Majorana scenario. Moreover, in the Majorana case the above observables contain the non-vanishing interference between V − A and V + A interactions, proportional to the T-even longitudinal ν e polarization. Our model-independent study is carried out for the flavor ν e eigenstates in the relativistic ν e limit.

Seven years ago, the GSI Online Mass Separator was decommissioned after 30 years of operation. The Golden Age of Jan Żylicz, celebrated at this Conference, is an adequate occasion to review the research performed at this facility. Its programme reached from nuclear-structure studies based on decay spectroscopy -the focus of this contribution -to investigations of nuclear shapes by means of laser spectroscopy all the way to experiments of astrophysical and fundamental-physics relevance. Reviewing this work I shall present my personal view on, firstly, examples of technical and scientific highlights and, secondly, the "humanistic" aspect of collaborating with many colleagues from abroad, including in particular Jan Żylicz and his associates from the University of Warsaw.
