Be 9 ( He 3 , p → ) B 11 polarization and implications for time-reversal invariance

Be 9 ( He 3 , p → ) B 11 polarization and implications for time-reversal invariance We have measured the polarization of protons from the Be 9 ( He 3 , p → ) B 11 reaction between 35° and 50° at an incident bombarding energy of 13.6 MeV to check claims of time-reversal noninvariance. We find complete disagreement with other polarization measurements for the same energy and angular range, but our results are in agreement with earlier measurements of the analyzing power in the inverse reaction initiated with polarized protons. Consequently we maintain that this reaction and its inverse exhibit no evidence for a violation of time-reversal invariance.

Abstract

We have measured the polarization of protons from the Be 9 ( He 3 , p → ) B 11 reaction between 35° and 50° at an incident bombarding energy of 13.6 MeV to check claims of time-reversal noninvariance. We find complete disagreement with other polarization measurements for the same energy and angular range, but our results are in agreement with earlier measurements of the analyzing power in the inverse reaction initiated with polarized protons. Consequently we maintain that this reaction and its inverse exhibit no evidence for a violation of time-reversal invariance.
