我们已经观察到，在相对论强度为10tw， 400fs的激光脉冲与沉积在聚酯薄膜上的氘化聚苯乙烯薄层的相互作用下，氘核加速到约2mev的能量。这些高能氘核被导向硼样品，在那里它们从10B(d,n)11C反应中产生了~ 105个正电子活性同位素11C原子。活化结果表明氘核是从靶体的前表面加速的。
We have observed deuterons accelerated to energies of about 2 MeV in the interaction of relativistically intense 10 TW, 400 fs laser pulse with a thin layer of deuterated polystyrene deposited on Mylar film. These high-energy deuterons were directed to the boron sample, where they produced ∼105 atoms of positron active isotope 11C from the reaction 10B(d,n)11C. The activation results suggest that deuterons were accelerated from the front surface of the target.
