Measurement of deep hole states in ^39K by ^40Ca(p,2p) reaction at 392 MeV
Abstract
The spectroscopic factor and the width of 1s1/2 state in ^40Ca have been deduced from ^40Ca(p,2p) reaction experiment. In the experiment the cross sections and analyzing powers of the ^40Ca(p,2p) reaction at 392 MeV have been measured. The strength distributions of the single-hole states in ^39K were successfully obtained by multipole decomposition analysis on the basis of the angular momentum L. The central value and the width (FWHM) of the obtained strength distribution of 1s1/2 are 52 MeV and 22 MeV. The obtained spectroscopic factor of 1s1/2 state is about 60% of the 2J+1. This value will be compared with the theoretical calculations that include short-range correlations and tensor correlations.
