Sc production from enriched TiO targets with a medical cyclotron.

Sc is a β-emitter which has been extensively studied for nuclear medicine applications. Its promising decay characteristics [t = 3.97 h, E [Formula: see text] = 632 keV (94.

Experimental assessment of nuclear cross sections for the production of Tb radioisotopes with a medical cyclotron.

Tb is one of the most interesting radionuclides for theranostic applications. It is suitable for SPECT imaging and it can be used as a true diagnostic partner of the therapeutic Tb and Tb. Its production by proton irradiation using enriched Gd and Gd oxide targets is currently being investigated and represents a promising solution.

Cross-section measurement of thulium radioisotopes with an 18 MeV medical PET cyclotron for an optimized Er production.

Er is a pure Auger-electron emitter with promising characteristics for therapeutic applications in nuclear medicine. The short penetration path and high Linear Energy Transfer (LET) of the emitted Auger electrons make Er particularly suitable for treating small tumor metastases. Several production methods based on the irradiation with charged particles of Er and Ho targets can be found in the literature.

Optimized production of Cu based on cross section measurements of Cu and Cu using an 18 MeV medical cyclotron.

RadioNuclide Therapy (RNT) in nuclear medicine is a cancer treatment based on the administration of radioactive substances that specifically target cancer cells in the patient. These radiopharmaceuticals consist of tumor-targeting vectors labeled with β, α, or Auger electron-emitting radionuclides. In this framework, Cu is receiving increasing interest as it provides β-particles accompanied by low-energy γ radiation.

New Limit on Axionlike Dark Matter Using Cold Neutrons.

We report on a search for dark matter axionlike particles (ALPs) using a Ramsey-type apparatus for cold neutrons. A hypothetical ALP-gluon coupling would manifest in a neutron electric dipole moment signal oscillating in time. Twenty-four hours of data have been analyzed in a frequency range from 23  μHz to 1 kHz, and no significant oscillating signal has been found.
