Collisions induced by Be9,10,11 on a Zn64 target at the same c.m. energy were studied. For first time, strong effects of Be11 halo structure elastic-scattering and reaction mechanisms energies near Coulomb barrier are evidenced experimentally.

Abstract Protontherapy is hadrontherapy’s fastest-growing modality and a pillar in the battle against cancer. Hadrontherapy’s superiority lies its inverted depth-dose profile, hence tumour-confined irradiation. Protons, however, lack distinct radiobiological advantages over photons or electrons. Higher LET (Linear Energy Transfer) 12 C-ions can overcome cancer radioresistance: DNA lesion complexity increases with LET, resulting efficient cell killing, i.e. higher Relative Biological...
The nuclear reaction known as proton-boron fusion has been triggered by a subnanosecond laser system focused onto thick boron nitride target at modest intensity (∼10^{16}W/cm^{2}), resulting in record yield of generated α particles. estimated value particles emitted per pulse is around 10^{11}, thus orders magnitude higher than any other experimental result previously reported. accelerated α-particle stream shows unique features terms kinetic energy (up to 10 MeV), duration (∼10 ns), and...

Accelerated proton beams have become increasingly common for treating cancer. The need cost and size reduction of particle accelerating machines has led to the pioneering investigation optical ion acceleration techniques based on laser-plasma interactions as a possible alternative.
