自从使用（e，e 'K+）反应研究超核光谱学的开创性实验E89-009完成后，在杰斐逊实验室进行了两个额外的实验E01-011和E05-115。这些后来的实验使用了一种改进的实验设计，即“倾斜法”，以显著抑制大的电磁背景，并允许光度的大幅增加。此外，还增加了一台新的K介子谱仪HKS（E01-011）、一台新的电子谱仪HES和一台新的分裂磁铁（E05-115），以产生新的精确、高分辨率的超核谱数据集。所有三个实验都获得了12 B-λ的光谱，这是最具特征的p壳层超核，通常用于校准。对这些不同实验的独立分析证明了极好的一致性，并提供了迄今为止由（e，e 'K+）反应产生的超核的最清晰的能级结构。本文介绍了这些实验的细节，以及所观察到的12 B-λ光谱的提取和分析。
Since the pioneering experiment E89-009 studying hypernuclear spectroscopy using the (e, e’K+) reaction was completed, two additional experiments, E01-011 and E05-115, were performed at Jefferson Lab. These later experiments used a modified experimental design, the "tilt method", to dramatically suppress the large electromagnetic background, and allowed for a substantial increase in luminosity. Additionally, a new kaon spectrometer, HKS (E01-011), a new electron spectrometer, HES, and a new splitting magnet (E05-115) were added to produce new data sets of precision, high-resolution hypernuclear spectroscopy. All three experiments obtained a spectrum for 12B-Lambda, which is the most characteristic p-shell hypernucleus and is commonly used for calibration. Independent analyses of these different experiments demonstrate excellent consistency and provide the clearest level structure to date of this hypernucleus as produced by the (e, e’K+) reaction. This paper presents details of these experiments, and the extraction and analysis of the observed 12B-Lambda spectrum.
