Abstract
The scattering of deuterons in helium gas has been investigated at three angles in the energy range 1000 to 1200 kev. A pronounced resonance appears at kev, of width 35 kev (lab), which corresponds to the 2.187-Mev level of . It is established that the level in question has , even parity, and a reduced width of the order of the single-particle limit. The best fit to the observations is obtained with a channel radius of 4.0× cm, taking into account the effect of the ground state, , which is assumed to have the same reduced width. A brief search, carried out at only one angle, revealed no further levels below Mev.
