/sup 140/Ce(d,p)/sup 141/Ce at 17 MeV. [Spectroscopic factors of /sup 141/Ce from (d,p) angular distributions]
The reaction /sup 140/Ce(d,p) has been studied at an incident deuteron energy of 17 MeV. Reaction protons were detected with an Enge split-pole spectrograph using a high-resolution position-sensitive (helix) gas counter and photographic emulsions as detectors. The energy resolution ranged from 11 to 13 keV. Angular distributions were measured in 3--5/sup 0/ steps for 6/sup 0/ < or = theta < or = 55/sup 0/. l-transfer assignments and spectroscopic factors have been deduced for 46 levels up to an excitation energy of 3.7 MeV in /sup 141/Ce by comparison with zero-range distorted-wave Born approximation calculations. We note that in spite of the neutron shell closure at N = 82, no /sup 141/Ce state has a spectroscopic factor in excess of 0.80. All neutron states are fragmented and considerable spectroscopic strength for l = 1 and 3 is spread up to and above 3 MeV. Two well resolved fragments each for the h/sub 9///sub 2/ and i/sub 13///sub 2/ states very nearly fill the sum rules for these single-particle states. The structure of /sup 141/Ce levels below 2 MeV is well reproduced by the unified model calculations of Heyde, Waroquier, and Vincx.
