New measurement of the B-11(p,alpha(0))Be-8 bare-nucleus S(E) factor via the Trojan horse method

Popis výsledku v původním jazyce

A new measurement of the 11 B(p,?0) 8 Be has been performed applying the Trojan horse method (THM) to the 2 H( 11 B,? 8 0 Be)n quasi-free reaction induced at a laboratory energy of 27 MeV. The astrophysical S(E) factor has been extracted from =600 keV down to zero energy by means of an improved data analysis technique and it has been compared with direct data available in the literature. The range investigated here overlaps with the energy region of the light element LiBeB stellar burning and with thatof future aneutronic fusion power plants using the 11 B+p fuel cycle. The new investigation described here con?rms the preliminary results obtained in the recent TH works. The origin of the discrepancy between the direct estimate of the 11 B(p,?0) 8 Be S(E)-factor at zero energy and that from a previous THM investigation is quantitatively corroborated. The results obtained here support, within the experimental uncertainties, the low-energy S(E)-factor extrapolation and the value of the e
