Angular Correlation Study of theMg24(d, pγ)Mg25Stripping Reaction as a Test of the Distorted-Wave Theory

Angular correlations between protons from the ${\mathrm{Mg}}^{24}(d, p){\mathrm{Mg}}^{25}$ reaction leading to the 3.40-Mev excited state of ${\mathrm{Mg}}^{25}$ and the resulting de-excitation gamma rays were investigated to test the validity of the distorted-wave stripping theory. A natural magnesium target was bombarded by 15-Mev deuterons and proton-gamma coincidences were counted using scintillation detectors in conjunction with conventional fast-slow coincidence circuitry. The correlations were studied at laboratory proton scattering angles of 15° and 45°, each in two mutually perpendicular planes: the reaction plane and the plane perpendicular to it containing the deuteron axis. The angular distribution of protons from this level was also measured and fitted by a Butler stripping curve with $l_n=1\mathrm{}$ and $r_0=5.0\mathrm{}$ fermis.
