“…For experimental studies of these reactions it is easier to produce beams of 14 O, 17 F, 21 Na, 25 Al, 29 P, 33 Cl and 37 K, via inverse (p,n) or (d,n) reactions, when compared to beams of 18 Ne, 22 Mg, 26 Si, 30 S, 34 Ar which require two-particle transfer reactions, such as ( 3 He,n) or ( 12 C, 10 Be). For that reason many of the relevant (α,p) reactions mentioned above have been studied via the time-inverse (p,α) reaction using radioactive beams that are closer to the valley of stability.…”
