Proton resonant states i. 22Mg h.ve been i.vesti.ated by th. resonant elasti.3}sc.tteri.g of 21Na+p. Th. 21Na beam wi.h.a mean energy of 4.00 MeV/u was separated by th. c.S radi.ac.i.e i.n beam separator(c.i.) and bombarded a th.c.(c.2)n target. Th. energy spec.ra of rec.i.ed protons were measured at sc.tteri.g angles of θc. ≈172° and 146°,respec.i.ely. A new state at 7.06 MeV h.s been observed c.early and anoth.r new one at 7.28 MeV i. tentati.ely i.enti.i.d due to i.s low stati.ti.3}. Th. proton resonant parameters were deduc.d from an R-matrix analysi. of th. di.ferenti.l c.oss sec.i.n data. Th. astroph.si.3}l resonant reac.i.n rate for th. 18Ne(α,p)21Na reac.i.n h.s been esti.ated,and i. i. about fi.e ti.es larger th.n th.t assumed before.
