Protron-Proton Bremsstrahlung at 204 MeV with a Polarized Beam
A proton-proton bremsstrahlung experiment has been completed using 204-MeV, 90% polarized protons incident on a liquid-hydrogen target. The gamma ray was detected in a threshold counter. The two protons were observed in a spark-chamber array giving energy and direction information. Cross sections an...

| 520 | |a A proton-proton bremsstrahlung experiment has been completed using 204-MeV, 90% polarized protons incident on a liquid-hydrogen target. The gamma ray was detected in a threshold counter. The two protons were observed in a spark-chamber array giving energy and direction information. Cross sections and gamma ray and proton asymmetries due to the polarized beam were measured. The cross sections obtained agree with the theoretical calculations of Sobel and Cromer, and Duck and Pearce. Ueda's calculation is high by a factor near 2, but properly describes the shape of (d2σdΩγdEγ) versus Eγ. Proton asymmetries agree in sign and magnitude with the elastic 210-MeV values. Gamma-ray asymmetries are of the same sign and magnitude as those obtained in our measurements of p+n→d+γ which agree with photodisintegration calculations. An upper limit of 35 nb has been placed on the production of p+p→p+p*(p*→p+γ) decaying to a gamma and a proton for lifetimes 10-22<~τ<~10-10 sec. | ||

Protron-Proton Bremsstrahlung at 204 MeV with a Polarized Beam |
| abstract |
A proton-proton bremsstrahlung experiment has been completed using 204-MeV, 90% polarized protons incident on a liquid-hydrogen target. The gamma ray was detected in a threshold counter. The two protons were observed in a spark-chamber array giving energy and direction information. Cross sections and gamma ray and proton asymmetries due to the polarized beam were measured. The cross sections obtained agree with the theoretical calculations of Sobel and Cromer, and Duck and Pearce. Ueda's calculation is high by a factor near 2, but properly describes the shape of (d2σdΩγdEγ) versus Eγ. Proton asymmetries agree in sign and magnitude with the elastic 210-MeV values. Gamma-ray asymmetries are of the same sign and magnitude as those obtained in our measurements of p+n→d+γ which agree with photodisintegration calculations. An upper limit of 35 nb has been placed on the production of p+p→p+p*(p*→p+γ) decaying to a gamma and a proton for lifetimes 10-22<~τ<~10-10 sec. |

Gamma-ray asymmetries are of the same sign and magnitude as those obtained in our measurements of p+n→d+γ which agree with photodisintegration calculations. An upper limit of 35 nb has been placed on the production of p+p→p+p*(p*→p+γ) decaying to a gamma and a proton for lifetimes 10-22<~τ<~10-10 sec. |

A proton-proton bremsstrahlung experiment has been completed using 204-MeV, 90% polarized protons incident on a liquid-hydrogen target. The gamma ray was detected in a threshold counter. The two protons were observed in a spark-chamber array giving energy and direction information. Cross sections and gamma ray and proton asymmetries due to the polarized beam were measured. The cross sections obtained agree with the theoretical calculations of Sobel and Cromer, and Duck and Pearce. Ueda's calculation is high by a factor near 2, but properly describes the shape of (d2σdΩγdEγ) versus Eγ. Proton asymmetries agree in sign and magnitude with the elastic 210-MeV values. Gamma-ray asymmetries are of the same sign and magnitude as those obtained in our measurements of p+n→d+γ which agree with photodisintegration calculations. An upper limit of 35 nb has been placed on the production of p+p→p+p*(p*→p+γ) decaying to a gamma and a proton for lifetimes 10-22<~τ<~10-10 sec. |
