摘要：

A vector-polarized deuteron beam of 52 MeV was used to excite proton-hole states via the (d(over arrow pointing right), He-3) reaction on Ar-36, Ar-38 and Ar-40. From the measured angular distributions of differential cross sections sigma(theta) and analyzing powers iT11(theta)we determined spins and parities J(pi) = 1/2+, 3/2+, 5/2+ and 1/2- of a number of isolated levels in Cl-35, Cl-37 and Cl-39 and the complete 1d hole strength distribution in the continuum region. Relative proton occupancies, single-particle energies, the shape of the Fermi surface and spreading widths were obtained from a combined analysis with proton stripping reactions on even argon isotopes. The deduced Id spin-orbit splitting is found to be consistent with the recently observed dependence on main quantum number n and mass number A. The mass excess of Cl-39 was determined to be (-29798 +/- 2.8) keV compared to a value of (-29804 +/- 19) keV as given in the mass tables.
