Tóm tắt

Gamow–Teller states, possibly with narrow widths, have been searched for by the 4 He (3 He , t) reaction with an energy resolution of 100 keV. The search is motivated by theoretical discussions on the role of pions in nuclear structure and simulation of supernovae explosion. In the preliminary analysis of the spectrum at around 0°, no significant narrow structure is observed.
