Ab initio calculations for non-strange and strange few-baryon systems
2018
Journal of Physics, Conference Series
Concerning the non-strange particle systems the low-energy excitation spectra of the three- and four-body helium isotopes are studied. Objects of the study are the astrophysical S-factor S_12 of the radiative proton deuteron capture d(p,γ)^3He and the width of the ^4He isoscalar monopole resonance.Both observables are calculated using the Lorentz integral transform (LIT) method. The LIT equations are solved via expansions of the LIT states on a specifically modified hyperspherical harmonics
