Measurement of tensor analyzing powers in deuteron photodisintegration.
نویسندگان
چکیده
A new accurate measurement of the tensor analyzing powers T20, T21, and T22 in deuteron photodisintegration has been performed. Wide-aperture nonmagnetic detectors allowed broad kinematic coverage in a single set up: E(gamma)=25 to 600 MeV, and theta(p)(cm)=24 degrees to 48 degrees and 70 degrees to 102 degrees . The new data provide a significant improvement over the few existing measurements. The angular dependency of the tensor asymmetries in deuteron photodisintegration is extracted for the first time.

We report a precision measurement of the deuteron tensor analyzing powers T(20) and T(21) at the MIT-Bates Linear Accelerator Center. Data were collected simultaneously over a momentum transfer range Q=2.15-4.50 fm(-1) with the Bates Large Acceptance Spectrometer Toroid using a highly polarized deuterium internal gas target. The data are in excellent agreement with calculations in a framework o...
متن کاملN ov 2 00 1 Irreducible pionic effects in nucleon - deuteron scattering below 20 MeV
The consequences of a recently introduced irreducible pionic effect in low energy nucleon-deuteron scattering are analyzed. Differential cross-sections, nucleon (vector) and deuteron (vector and tensor) analyzing powers, and four different polarization transfer coefficients have been considered. This 3N F-like effect is generated by the pion-exchange diagram in presence of a two-nucleon correla...

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...
متن کاملLow-Energy Deuteron Polarimeter
We built a Low Energy Deuteron Polarimeter (LDP) which measures the spin-polarization of deuteron beams in the energy range of 25 to 80 keV. The LDP works by measuring azimuthal asymmetries in the D(~ d, n)He reaction at θlab = 90 ◦ and comparing them to analyzing powers. We built this polarimeter for two reasons. Firstly, to crosscheck other polarimeters at KVI (LSP and IBP). Secondly to test ...

Tensor analyzing powers in forward angle exclusive π-meson photoproduction on deuteron. Abstract The target tensor analyzing powers of the process γd → π − pp had been studied in the plane wave impulse approximation, if both ejected protons are detected in coincidence and in the directions, symmetrical respect to the incoming photon momentum , being in the proton plane. The matrix elements of t...
