Résumé
The spectrum of $\rm ^He$ was studied by means of the $\rm ^He, p)^He$ reaction at a laboratory energy of 25 $\rm MeV/A$ and small center-of-mass angles. Missing mass spectrum of $\rm ^He$ was derived from the obtained p-8He coincidence. A resolution of 0.7 MeV was achieved in this spectrum for the measured $\rm ^He$ 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 $\rm ^He$ g.s. resonance.
