Production theory extended from p-shell to sd-shell hypernuclei with double strangeness

成功地计算了(K-，K+)与^&lt；12&gt；C靶的反应截面，表明Ξ超核激发函数敏感地依赖于Ξ-N相互作用的自旋-自旋性质。壳层模型程序已扩展到处理典型的SD壳层超核，包括了核激发组态。分析了^&lt；19-20&gt；_ΛF和^&lt；19-20&gt；_ΛNe的结构，并用波函数估算了(K-，π-)，(π+，K+)和(γ，K+)反应的激发光谱。对于p壳层和更重的Λ超核(^&lt；28&gt；Al，^&lt；40&gt；K和^&lt；52&gt；Ti)的预测与杰斐逊实验室的实验数据符合得很好。

(K-, K+) reaction cross section with the^<12> C target was successfully calculated in DWIA, suggesting that theΞ-hypernuclear excitation function is sensitively dependent on the spin-spin property of theΞ-N interaction. The shell-model code has been extended to treat typical sd-shell hypernuclei by including the core-excited configurations. Structures of^<19-20>_ΛF and^<19-20>_ΛNe have been analyzed and the wave functions are used to estimate the excitation spectra of the(K-,π-),(π+, K+) and(γ, K+) reactions. The predictions for p-shell and heavierΛ-hypernuclei(^<28> Al,^<40> K and^<52> Ti) are in good agreement with the experimental data from the Jefferson Laboratory.
