(d, p) stripping reaction and (d, d) elastic scattering on Cr50, Cr52, Cr53, Cr54 and Fe54, Fe56 and Fe57

Investigation of levels in59Ni following the ?+ decay of59Cu

“…However this level was indicated in several stripping reaction measurements [10][11][12] and was also confirmed by Stelson et al [5] from (p, n) and (p, nT) charge exchange reactions. Vervier has listed J~ = 5/2-or 7/2-for this state.…”

Angular Correlation Measurements in 57Fe

“…The measurements of the proton angular distributions in the 56Fe(d, p) 57 Fe reaction are consistent with the value of I = 1 for the captured neutron for both levels (Cohen et al 1962;Bochin et al 1964;Sperduto and Beuchner 1964;Sen Gupta and Hannan 1967), and these results limit the spins of the levels to 1/2-or 31T. The other method used by Kopecky and Warming (1969) was to measure the circular polarization of the y-rays following the capture of polarized thermal neutrons.…”

“…Most of the proposed spin assignments above 1 MeV have been obtained from the angular distributions of protons from the 56Fe(d, p) 57 Fe reaction (Cohen et al 1962;Bochin et al 1964;Sperduto and Beuchner 1964;Sen Gupta and Hannan 1967;Rapport 1970), which normally give two possible values. There are two states in 57Fe at 1·627 and 1·725 MeV which are strongly populated in the 56Fe( n(thermal), y) 57 Fe reaction and decay predominantly to the first excited state (14 keV) and ground state respectively.…”

Nuclear Spectroscopy inCr52,Cr53, andWhitten1 1967Phys. Rev.

“…lations 65 predict that 67% of the Cr 50 ground-state wave function is the configuration {(^/7/2 4 ) 0 (y/7/2~~2) 0 } 0 , while Cr 50 (d,^)Cr 51 reaction studies 45,66 show that the 0.776-MeV level has a large 2^3 /2 single-particle component. The Q values of these two transitions are within 500 keV of each other, so that their absolute cross sections are about equal: J<r/dO(35 0 ) = 110±10 jub/sr for Cr 53 (^/)Cr 51 f~ 0.776 MeV, Q= -12.282 MeV while da/dto(3S°) = 9Q±10 /zb/sr for Cr 52 (^,/)Cr 50 g.s., <2=-12.811 MeV.…”
