Injection of high energetic ion beams to superfluid helium as a host matrix of laser spectroscopic study of radioisotope atoms

We are develo** a laser spectroscopic method to study the nuclear structure of radioactive isotopes utilizing superfluid helium (He II) as an efficient stopper for highly energetic ion beams and as an in-sit...

Space weathering record and pristine state of Ryugu samples from MicrOmega spectral analysis

The samples returned from asteroid Ryugu were collected both at its surface and at its subsurface by Hayabusa2 and can, thus, provide information on the space weathering of C-type asteroids at different depths...

Medical ¹⁵O production via the ¹⁶O(γ,n)¹⁵O reaction for blood flow examination

We propose a new scheme for producing medical ¹⁵O isotopes using a water target, for blood flow examination with Positron Emission Tomography. The ¹⁵O radioisotopes are produced via the ¹⁶O(γ,n)¹⁵O reaction in a ...
