Abstract

We have calibrated the analyzing power A_y in proton-carbon elastic scattering at 71.2 MeV via double-scattering with polarized beam. An accuracy of ±0.001 was achieved using a highly efficient setup (statistical uncertainty of ±0.0003) and a new type of analysis based on asymmetry ratios. Our result A_y=0.986±0.001 may indicate the existence of a point with A_y=1 near 65 MeV.

Polarization transfer in 2H(p→, n→)pp
1999, Nuclear Physics A
We measured the 0° polarization transfer of the $^{2} H (p, n)pp$ reaction used to produce a high-intensity, monoenergetic neutron beam. The 0⁺ → 0⁺ reaction $^{14} C (p, n)^{14} N (2.31)$ has been used to calibrate a high-efficiency polarimeter, which in turn was used to measure the polarization transfer in $^{2} H (p, n)pp$ . With this data the uncertainty on the polarization of the 70 MeV neutron beam, used for many different studies at PSI, is reduced to 1.1%. The data are compared to predictions of Faddeev calculations based on realistic nucleon-nucleon interactions.
Problems and advantages of measuring parity and time-reversal invariance in nuclei
1998, Nuclear Physics A
In the low energy regime parity violation for pure hadronic systems can be expressed essentially by six effective weak meson-nucleon coupling constants, three of which are only known at present. Additional independent experiments have been proposed involving light, heavy and compound nuclei, to determine all six coupling constants unambiguously. Though heavy nuclei offer enhancement factors of up to (10⁵), the difficulty to extract relevant weak meson-nucleon coupling constants from experiments involving heavy nuclei increases substantially. In this context the statistical model of compound nuclei provides an additional option for the extraction of these coupling constants.
In contrast to parity violation (PV) tests, time-reversal in variance (TRI) information that is extracted from 2-body reactions, results from a comparison of two different observables. As a consequence, the accuracy of these experiments is reduced. In view of the mechanisms that enhance PV, TRI tests have been performed that utilize heavy nuclei too. At COSY a novel, true T-odd, P-even null-experiment has been proposed that has the potential to test TRI to an accuracy of 10⁻⁶ in $p$ - $d$ -scattering. For this test the COSY ring serves as accelerator, ideal forward spectrometer and detector.

Measurement of the analyzing power A<inf>y</inf> in neutron-proton radiative capture at E<inf>n</inf> = 68 MeV
1994, Nuclear Physics, Section A
The vector analyzing power A_y for the reaction $^{1} H (n, γ)^{2} H$ has been measured at five angles between 60° and 140° in the lab at an incident neutron energy of 67.7 MeV. The measurement is of a presision never before acheived (ΔA_y ⩽ 0.01, statistical) for this observable. This precision makes possible a quantitative comparison with meson-exchange theories, thus enhancing our understanding of the role of non-nucleonic degrees of freedom.
Depolarization in proton-6Li elastic scattering
1994, Nuclear Physics, Section A
We have measured the differential cross section dσ/dΩ, the analyzing power A_y and the depolarization parameter D for p-⁶Li elastic scattering at 72 MeV. The spin/isospin character of this transition and the large spinflip effects observed make p-⁶Li elastic scattering a good case to study the isoscalar spinflip component of the effective force. The data were fitted by a conventional optical-model potential which included a real, spherical spin-spin potential with surface form factor and V_ss = 5.3 ± 1.0 MeV. A qualitative description of the data was also achieved with a “semi-microscopic” folding calculation based on the density-dependent Paris effective force, shell-model wave functions and a phenomenological optical-model potential.
