Structure of 3He in backward elastic p-3He scattering

BACKWARD ELASTIC p 3He-SCATTERING AND HIGH MOMENTUM COMPONENTS OF 3He WAVE FUNCTION

It is shown that owing to a dominance of np−pair transfer mechanism of backward elastic p Hescattering for incident proton kinetic energies Tp > 1 GeV the cross section of this process is defined mainly by the values of the Faddeev component of the wave function of He nucleus, φ(q23,p1), at high relative momenta q23 > 0.6GeV/c of the NN-pair in the S0− state and at low spectator momenta p1 ∼ 0−...

The A(y) problem for p-3He elastic scattering.

We present evidence that numerically accurate quantum calculations employing modern internucleon forces do not reproduce the proton analyzing power, A(y), for p- 3He elastic scattering at low energies. These calculations underpredict new measured analyzing powers by approximately 30% at E(c.m.) = 1.20 MeV and by 40% at E(c.m.) = 1.69 MeV, an effect analogous to a well-known problem in p-d and n...

Thermodynamic properties of the ionized gas 3He

In this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3He atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. To perform the calculations, we have considered the kinetic term, and Coulomb interaction between the particles in our Hamiltonian. The calculated properties are free ener...
