Measurement E88M1

Experiment: Measurement of 2- and 3- Nucleon Short Range Correlation Probabilities in Nuclei
Year: 2002

Experiment comment:

Using the measured onsets of 2- and 3-nucleon SRC, combined with the well known wave functions of deuterium and 3He, the absolute probabilities of these correlations were extracted, too.
