“…To study the reactions of two unstable particles ( 7 Be and n), we applied the Trojan horse method (THM, see References in [6,8]), which is an indirect method to study a 2body reaction via a 3-body reaction measurement under a quasi-free kinematical condition. The 7 Be(n, α) 4 He reaction had been measured with the THM in a previous work [8], and our new work expanded the sensitivity also to the 7 Be(n, p 0 ) 7 Li and 7 Be(n, p 1 ) 7 Li * reactions, by achieving a sufficient energy resolution to separate the contributions of these two reactions. √ E cm of the 7 Be(n, p 0 ) 7 Li, 7 Be(n, p 1 ) 7 Li * and 7 Be(n, α) 4 He reactions in [6] are shown as open red circles, blue triangles, green squares, respectively.…”
