The elastic scattering of 162 MeV л± from 13C and the excitation function of 13C（л+,л0）13N are analyzed in the frame of the Glauber *** nuclear wave function is assumedto be constructed by a valence nucleon plus a core of 12C which is described by an independent αcluster model.A good agreement between the theory and experiment is obtained.

Systematic calculations on low-lying states of Os,Ir,Pt,Au,Hg and Tl neutron-deficient isotopes in the A～210 region have been carried out by using the nucleon pair approximation(NPA) of the shell model. We calculate binding energies of the ground states,low-excited level scheme,electric quadrupole,magnetic dipole moments and E2 transition rates,many of which have not yet been measured in the *** results reasonably consistent with the available experimental data.

Lejeune Center of theoretical nuclear physics, national laboratory of heavy ionaccelerator, lanzhou 73.000, P.R. china Institute of Modern physics, Academia Sinica, lanzhou 73.000, P.

＜正＞A microscopic three-body force is introduced in the Brueckner-Hartree-Fock ap-proach and its effects on the the nuclear symmetry energy and the proton fractionin the β-equlibrium matter have been investigated. It is shown that the three-bodyforce leads to a decisive improvement of the saturation properties for symmetricnuclear matter and a large enhancement of the symmetry energy at high density.

A general network decoupling method for phased array radio frequency coil used in magnetic resonance imaging is devel-oped. A more flexible digital approach further simplifies the method, which has an even higher signal-to-noise ratio. The performance ofthe digitalized decoupling method was confirmed by the calculated result by using a high frequency structure simulation software with themethod of finite element for a tree-port phased array RF coil. The consistence was well established between the theoretical and simulatedresults.

The differential cross sections and integrated cross sections of the 6Li(n,t)4He reaction were measured at 1.85 and 2.67 MeV by using a gridded ionization chamber. Neutrons were produced through the T(p,n)3He reaction. The absolute neutron flux was determined through the 238U(n,f) reaction. Present results are compared with existing data.
