This paper extends the Goldfarb-Buttle method which is used to treat the single particle transfer reactions induced by heavy ions to multi-particle transfer reactions. The ~(12)C(~7Li, t)~(16)O and ~(20)Ne(d, ~6Li)~(16)O reactions are calculated by using the coherent wave function for (16)O, with due consideration to certain recoil effects. The results are compared with those obtained by experiment.

本文把用于处理重离子引起的单粒子转移反应的Goldfarb-Buttle方法推广到多粒子转移反应。计算了~(12)C(~7Li,t)~(16)O和~(20)Ne(d,~6Li)~(16)O反应,用了~(16)O的全相干波函数,考虑了某些反冲因素,并将结果与实验作了比较。

Formulae for the nuclear pairing-rotational (p.r.) and pairing-vibrational (p.v.) spectra are obtained using the PNC (particle-number-conserving) method. The quentum numbers characterizing the p.r. band, the braching ratios and the selection rule for two-particle transfer reactions are given. It is shown that the pairing-rotational scheme holds even for those nuclei near closed-shell, provided that the major-shell is not crossed. The anharmonic p.v. spectrum is shown to be equivalent to two sets...

Formulae for the nuclear pairing-rotational (p.r.) and pairing-vibrational (p.v.) spectra are obtained using the PNC (particle-number-conserving) method. The quentum numbers characterizing the p.r. band, the braching ratios and the selection rule for two-particle transfer reactions are given. It is shown that the pairing-rotational scheme holds even for those nuclei near closed-shell, provided that the major-shell is not crossed. The anharmonic p.v. spectrum is shown to be equivalent to two sets of p.r. bands. The physical meaning of the parameters occuring in the p.r. and p.v. spectra is discussed.

本文用处理对力的粒子数守恒方法得出了原子核对转动及非简谐对振动能谱公式.给出了对转动带的量子数、二核子传递反应分支比及选择定则.转动谱中粒子数平方项系数近似等于费米面附近的单粒子能级平均间距.在不跨越大壳情况下(包括在满壳附近),对转动谱公式仍然适用.非简谐对振动能谱公式与两套对转动谱公式等价.公式中线性项(振子能量)近似等于费米面处单粒子能级的间隙.振子相互作用能与满壳之上(下)的单粒子能级平均间距的两倍大略相等.非简谐效应对于能谱及二核子传递反应分支比都有重要影响.

Two-particle transfer reaction ~(38)Ar (~(11)B,~(9)Be) ~(38)K has been produ-ced by using a beam of 115 Mev of ~(11)B.A counter-telescoper is used tomeasure the spectra of the reaction products at=8,Three peaks of en-ergy level ~(38)K(3~+,7~+, 5~+) has been observed.DWBA calculation hasbeen performed for single-particlc transfer reaction and the optical pa-rameters checked.Supposing the reaction mechanism of ~(36)Ar(~(11)B,~9Be)~(38)K is the sequential mode,the CRC calculation has been performed toget the cross section.The good agreement between the theoretical crosssection and experimental one shows that the dominant reaction mechani-sm for ~(36)Ar(~(11)B,~9Be)~(38)K appears to be the sequential mode.

用115Mev~(11)B 束轰击~(36)Ar 产生两核子转移反应,用固体探测器望远镜在θL=8°处测量了反应产物的能谱,观察到~(38)k 的3~+,7~+和5~+等三个能级.对有关的单核子转移反应用 DWBA 进行了计算,以检验束缚态和光学模型参数.用壳模型计算了有关核的谱幅度.最后,假定反应机制是顺序转移的多步过程,用耦合反应道理论(CRC)计算了截面.理论截面与实验截面比较的结果表明,顺序转移可能是该反应的主要机制.
