| dc.description | An 18 in. diffusion cloud chamber filled with 28 atmospheres of hydrogen and in a magnetic field of 11 200 gauss is used to investigate the production of π<sup>+</sup>-mesons in p-p collisions at 383 MeV. The energy resolution is of the order of 2 MeV and the spectrum obtained can be divided into mesons from the `bound' and `unbound' reactions. The angular distributions found are dσ/dω (bound) ∝ (0.19 ± 0.06) + cos<sup>2</sup> θ' and dσ/dω (unbound) ∝ (0.21 ± 0.07) + cos<sup>2</sup> θ'. The branching ratio σ (unbound)/σ (total) = (47 ± 8)%. The shape of the unbound spectrum is not in agreement with that predicted by the phenomenological theory but this spectrum and also the high experimental branching ratio can be explained by the inclusion of a term σ<sub>10</sub>'' (Pp) ≃ 1.2η<sub>max</sub><sup>8</sup> in the theory. |
