Polarization of Protons inC12(d, p)C13

Polarization of Protons inBe9(d, p)Be10

“…However, in the region of the stripping peak, the importance of the spin-orbit terms is not so clear. In neither this, nor in the early carbon data 11,12 does the polarization exceed the limits placed on it by the central potential theory. Indeed, distortedwave calculations on C 12 (d,£)C 13 by Gibbs, 28 using spinorbit potential, show considerably polarization at high angles but comparatively little in the forward direction.…”

“…At every angle, the polarization is smaller in magnitude and opposite in sign to that for the carbon reaction 11,12 at the same bombarding energy (except in the region of sign change). The experimental errors are such that it is difficult • to fix a definite ratio of the polarizations in carbon and beryllium, but \PBB/PG\ seems to be greater than the value 1/2 which is expected from Eq.…”

“…The rapid change of sign between 10 and 11.4 MeV is extremely interesting in view of the small variation with energy (measurements from Ed=7 to 15 MeV) of the polarization in the reaction C 12 (d,/>)C 13 to the ground state. [11][12][13] It would be of great interest to have some additional measurements of the polarization in the reaction B 10 (d,£)B n in the interval of Ed-10 to 12 MeV to see how it varies with energy.…”

“…The reaction Be 9 (d,£)Be 10 has been selected to complement the measurements which have been performed on carbon. 11,12 The two reactions should have roughly the same optical wave functions since the I values are the same, the nuclear radii are similar, and the Q values differ by less than 2 MeV. They differ primarily in the total angular momentum transfer; C 12 (d,p)C 13 has j = /-J while Be 9 (d,^)Be 10 has j=l+%.…”
