MEASUREMENTS OF INPLANE POLARIZATION TRANSFER COEFFICIENT IN 24Mg(p,p') REACTION AT Ep=65 MeV

Model for the Quasifree Polarization-Transfer Measurements in the (p,n) Reaction at 495 MeV

The recent (~ p, ~n) polarization transfer experiments show the ratio of spin-longitudinal to spin-transverse response functions RL/RT , measured at a three-momentum transfer of 1.72 fm in C and Ca, to be essentially unity for small projectileenergy loss. This can be explained theoretically if the nucleon-nucleon tensor interaction is zero at this momentum transfer. We can partially achieve thi...

np elastic spin-transfer measurements at 485 and 635 MeV.

'Current Address: Los Alamos National Laboratory, Los Alamos, NM 87545. t Current Address: PSI, LG I25, CH 5232 Villigen PSI, Switzerland. ~ Deceased. coefficients as high as 76%." "To stabilize the solution, Wolfenstein (spin-transfer) parameter data are required of similar quality to those at 800 MeV. " We present these new data here. With the inclusion of these data, Bugg reports stable solu...

Adiabatic transfer of net electron polarization to nuclear polarization

A new type of spin chemical experiment is suggested which utilizes adiabatic reversion of a low magnetic Bo field for an efficient transfer of net electron spin polarization, as arising from some CIDEP mechanism, to the nuclear polarization of radicals. After trapping the radicals in diamagnetic products and transferring the sample to a NMR probe, the adiabatic polarization transfer effect can ...

The electron depolarization during dynamic nuclear polarization: measurements and simulations.

Dynamic nuclear polarization is typically explained either using microscopic systems, such as in the solid effect and cross effect mechanisms, or using the macroscopic formalism of spin temperature which assumes that the state of the electrons can be described using temperature coefficients, giving rise to the thermal mixing mechanism. The distinction between these mechanisms is typically made ...
