Resonance Levels in the Reactions ²⁸Si(p, γ)²⁹P, ²⁹Si(p, γ)³⁰P and ³⁰Si(p, γ)³¹P

Abstract

The reactions ²⁸Si(p, γ)²⁹P, ²⁹Si(p, γ)³⁰P and ³⁰Si(p, γ)³¹P have been studied in the region of proton energy from 300 kev to 1700 kev. We have found in the reaction ²⁹Si(p, γ)³⁰P two new resonances at proton energies 1307.5±3 kev and 1331.5±3 kev, and in the reaction ³⁰Si(p, γ)³¹P nine new resonances at proton energies 1094, 1179.5, 1209.5, 1290.5, 1300, 1302.5, 1324.5, 1394.5 and 1403 kev with the errors of ±3 kev. No definite resonant level has been observed in the reaction ²⁸Si(p, γ)²⁹P in the range of proton energy between 570 kev and 1400 kev.
