J.Kirscher, H.W.Griesshammer

Asymmetric regularization of the ground and excited state of the ⁴He nucleus

NUCLEAR STRUCTURE ³H, ^3,4He; calculated two- and three-nucleon systems threshold structure sufficient to predict a pair of 4-nucleon states, one of them identified with α-particle and a shallow unstable state close to triton-proton threshold consistent with data of the first excited state of ⁴He using the framework of Pionless EFT; deduced diagonal ³H-p ¹S₀ phase shift in the α-channel with respect to short-distance structure of nuclear interaction, increasing sensitivity of nuclei to neutron-proton P-wave interaction.
