EVALUATion OF NEUTRON nuclear DATA FOR 240Pu

粒子加速器学会第七届全国会员代表大会暨学术报告会

作者： J.W. Xia, W.L. Zhan, B.W. Wei, CSR group Institute of Modem physics (IMP), chinese academy of sciences P.O. Box 31, lanzhou, 73.000, PR. china

＜正＞1. Introduction From May of 1993 to November of 1996, a new plan was proposed [ 1,2] to upgrade the HIRFL [3] with a multi-functional Cooling Storage Ring （CSR） forming a HIRFL-CSR accelerator system shown in Fig. 1. This will greatly enhance the performances of HIRFL for those researches by using Radioactive ion Beams （RIB） and high-Z heavy ion beams in the fields of nuclear physics and atomic physics. In July of 1998, the chinese center government approved this plan, and on December 10 of 1999 the CSR project was started. The

According to A. B. Migdal’s prediction that a pion condensate should exist in ordinaryfinite nuclei, a nucleon density modulation due to pion condensate has been obtained frompseudovector pion nucleon coupling and phenomenological effective repulsion *** on the nucleon density modulation, we study the effects of pion condensate in somenuclear phenomena, such as high energy particle nucleus scattering, X-ray energy spectrumof muonic atom and nuclear binding *** results strongly indicate that there aresome sufficient opportunities in these processes for pion condensate to manifest itself andthe condensate could help us to improve the agreement between theory and experiments formany processes.

Introduction Calcium is one of the most important structural materials. The abundance ofCa in natural calcium is 96.94%, soCa(n,α) data are very important in nuclear engineering. As we know, experimental data forCa(n,α) reaction are scarce and there are large differences among them. AlthoughCa is a double magic nucleus, theoretical calculation ofCa(n,α) data is difficult to fit experimental ones. Reliable data are needed for the study of reaction mechanism.
