| Abstract: | The spectrum of 10He was studied by means of the 3H(8He, p)10He reaction at a laboratory energy of 25 MeV/A and small center-of-mass angles. Missing mass spectrum of 10He was derived from the obtained p-8He coincidence. A resolution of 0.7 MeV was achieved in this spectrum for the measured 10He energy. Most likely, a well isolated group of 10 events detected between 2 and 5 MeV and showing a maximum at about 3 MeV in the spectrum of the present work exhibits the 10He g.s. resonance. |
