摘要：

We propose to search for the He-4 - eta bound state via measurement of the excitation functions for the dd -> (3)Hp pi(0), (3)Hn pi(+), (3)Hen pi(0),(3)Hep pi(-) reactions where the outgoing N - pi pairs originate from the conversion of the eta meson on a nucleon inside the He-4 nucleus. Precise determination of the profile of the expected Breit-Wigner distribution in the excitation curves will allow to determine the binding energy and the width of the He-4 - eta bound state.
