Investigating the three-nucleon force through [superscript 10]C(p,p)[superscript10]C

Abstract

We present the first effort to understand the effect of the three-nucleon force on the angular distribution of nucleus-proton scattering near the drip-line. We successfully performed the elastic scattering of the unstable nucleus [superscript 10]C with a proton target using the ISAC Charged Particle Reaction Spectroscopy Station (IRIS) facility stationed at TRIUMF, Canada. The facility utilizes a novel thin windowless solid H[subscript 2] target which made the reaction study possible with a beam intensity of ~ 2:5X10[superscript 3] pps. The angular distribution measurement was based on the detection of the protons with the thin Si and CsI(Tl) detectors. We compared the measured cross section with the predictions made by ab initio no core shell model with continuum (NCSMC) based on the chiral NN (N[superscript 3]LO) and 3N (N[superscript 2]LO) forces. The study shows that the measured angular distribution is in better agreement with the theoretical prediction based on the chiral NN+3N forces.
