description: The energy of gamma rays from the reaction H² (p,γ)He³ has been measured as a function of incident proton energy in the range of proton energies from 1 to 2 Mev. The results were consistent with the assumption that the He³ is left in the ground state. The Doppler shift in gamma ray energy was measured for incident protons of energies 1 Mev. and 1.7 Mev. and was found to be consistent with the value calculated assuming that the He³ was not slowed down before emission of the gamma ray. This puts an upper limit on the lifetime of the intermediate state of 2 x 10⁻¹² sec. The angular distribution of gamma rays at an incident proton energy of 1.75 Mev. was of the form sin²θ + (.025 ± .007), and at incident proton energy of 1.00 Mev. was of the form sin²θ + (.043 ± .008). The excitation function, over a range of incident proton energies from 0.25 to 1.85 Mev., is fitted by a function of the form AEp⁰•⁶⁵.

note: I. A STUDY OF THE GAMMA RAYS PRODUCED BY THE BOMBARDMENT OF DEUTERIUM WITH PROTONS by EUGENE CRITOPH A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF APPLIED SCIENCE i n the Department of PHYSICS We accept t h i s thesis as conforming to the standard required from candidates f o r the degree O f MASTER OF APPLIED SCIENCE Members of the Department of Physics THE UNIVERSITY OF BRITISH COLUMBIA November, 1955 I l l ABSTRACT The energy of gamma rays from the reaction H 2 (p,Y)He^ has been measured as a function of incident proton energy i n the range of proton energies from 1 to 2 Mev. The results were consistent with the assumption that the He^ is l e f t i n the ground state. The Doppler s h i f t i n gamma ray energy was measured fo r incident protons of energies 1 Mev. and 1.7 Mev. and was found to be consistent with the value calculated assuming that the He^ was not slowed down before emission of the gamma ray. This puts an upper l i m i t on the l i f e t i m e of the intermediate state of 2 x IO""12 sec. The angular d i s t r i b u t i o n of gamma rays at an incident p proton energy of 1.75 Mev. was of the form s i n 6 + ( . 0 2 5 ± .007), and at incident proton energy of 1.00 Mev. was of the form s i n 2 6 + (.043 ± .008). The e x c i t a t i o n function, over a range of incident proton energies from 0 . 2 5 to 1.85 Mev.,is f i t t e d by a function of the form A E p 0 , 6 5 . . IV ACKNOWLEDGrMENTS I would l i k e to acknowledge the receipt of a National Research Council Bursary f o r the year 1951-52, without which t h i s work could not have been done. I would also l i k e to thank Dr. J.B. Warren and Dr. CA. Barnes, under whose supervision t h i s work was done, and Dr. G-.M.
