Neutron Groups from Deuteron Stripping by²³Na,²⁷Al and³¹P

Using a triple ionization chamber to collimate and record recoil protons from a hydrogenous radiator, angular distribution measurements have been carried out on a number of neutron groups emitted as a result of the bombard by 9MeV deuterons of targets of sodium carbonate, aluminium and phosphorus. Spins and parities of the resulting states of the 4n nuclei 24 Mg, 28 Si and 32 S have been assigned by applying the theory of the stripping process. In the case of 28 Si, the first T = 1 level is identified and its characteristics compared with those of the ground state of 28 Al.
