1. Diffuse relaxation approximation in a heated Fermi system.

Author

Lukyanov, S. V.

Subjects
*SURFACE diffusion, *FERMI surfaces, *DIFFUSION coefficients
Abstract

An expression for the two-particle relaxation time of collective excitations on a distorted Fermi surface in the diffusion approach to kinetic theory is obtained. The general case of momentum-dependent diffusion and drift coefficients is considered. The temperature dependence of the obtained expression is established. [ABSTRACT FROM AUTHOR]

Abstract

We have measured the differential cross-sections for the elastic as well as inelastic scattering populating the 2.43 MeV (5 / 2 −) excited state in 9 Be using 3 He beams at energies of 30, 40 and 47 MeV on a 9 Be target. The experimental results for the elastic scattering were analyzed within the framework of the optical model using the Woods–Saxon and double-folding potentials. The theoretical calculations for the concerned excited states were performed using the coupled-channel method. The optimal deformation parameters for the excited states of 9 Be nucleus were extracted. [ABSTRACT FROM AUTHOR]

Abstract

We suggest the diffuse approach to the relaxation processes within the kinetic theory for the Wigner distribution function. The diffusion and drift coefficients are evaluated taking into consideration the interparticle collisions on the distorted Fermi surface. Using the finite range interaction, we show that the momentum dependence of the diffuse coefficient Dp(p) has a maximum at Fermi momentum p = pF whereas the drift coefficient Kp(p) is negative and reaches a minimum at p ≈ pF. For a cold Fermi system the diffusion coefficient takes the nonzero value which is caused by the relaxation on the distorted Fermi surface at temperature T = 0. The numerical solution of the diffusion equation was performed for the particle-hole excitation in a nucleus with A = 16. The evaluated relaxation time τr ≈ 8.3 ⋅ 10-23s is close to the corresponding result in a nuclear Fermi-liquid obtained within the kinetic theory. [ABSTRACT FROM AUTHOR]

Abstract

To investigate the structure of two-neutron halo we propose an experimental method of studying neutron-neutron correlations by measuring reactions induced by halo projectile in nuclear photoemulsions. The obtained preliminary data on interaction of halo nucleus 6He with hydrogen are compared with results of simple kinematical calculations for the reaction of quasi-free scattering of proton by the clusters existing in halo nucleus 6He.
