The levels of $sup 53$Mn populated by the reactions $sup 52$Cr($sup 3$He,d)$sup 53$Mn at 24 MeV and $sup 52$Cr($sup 7$Li,$sup 6$He)$sup 53$Mn at 34 MeV were studied using the Florida State University quadrupole spectrometer. Angular distributions were taken from 5degree to 60degree for $sup 52$Cr($sup 3$He,d)$sup 53$Mn, and from 1degree to 25degree for the $sup 52$Cr($sup 7$Li,$sup 6$He)$sup 53$Mn reaction. Angular distributions show the expected L-dependent shapes which are well described by the DWBA. Relative spectroscopic factors are in excellent agreement with previous studies. The J-dependent shape of the ($sup 7$Li,$sup 6$He) angular distributions at forward angles is used to identify the 2.68 and 3.48 MeV levels as P$sub 1$$/$$sub 2$, and the 4.07 and 4.43 MeV levels as p$sub 3$$/$$sub 2$. Absolute spectroscopic factors for the two reactions are in very good agreement and are about 30% lower than the values of previous studies. Seventeen levels of $sup 53$Mn above 6 MeV are observed in one or both reactions. Angular distributions for eight levels are extracted for the ($sup 3$He,d) reaction, including the three isobaric analog levels at 6.97, 7.54, and 8.03 MeV. Several of the levels above 6 MeV exhibit angular distributions which might be interpreted as being for either l=3 or l=4 transferred. These levels are identified as g-wave final states on the basis of their strength and excitation energy. The spectroscopic factors for the unbound levels are derived by a technique of extrapolation of crosssections from the bound state analysis. The spectroscopic factors extracted for the isobaric analog levels are consistent with (d,p) results to the parent states, within the limitations of the analysis. (AIP)
