Abstract

Neutron production from targets of Be, C, Mo, Cu, Ta and Au bombarded with deuterons of 16, 33 and 50 MeV has been studied at the isochronous cyclotron at Louvain-la-Neuve. Neutron spectra were measured by the time of flight method. The yields of neutrons and gamma rays were also measured, and the greatest ratio of neutrons to gamma rays in the forward direction was found to occur with 50 MeV deuterons on a Be target. The angular distribution of neutrons from Be was measured at 16, 33 and 50 MeV, and neutron spectra were measured as function of angle with 50 MeV deuterons on Be.

摘要

在鲁汶新镇的等时回旋加速器上，研究了用能量为16兆电子伏、33兆电子伏和50兆电子伏的氘核轰击铍、碳、钼、铜、钽和金靶时产生中子的情况。用飞行时间法测量了中子能谱。还测量了中子和伽马射线的产额，发现用50兆电子伏的氘核轰击铍靶时，向前方向的中子与伽马射线的产额比最大。在16兆电子伏、33兆电子伏和50兆电子伏下测量了铍靶产生的中子的角分布，并用50兆电子伏的氘核轰击铍靶，测量了中子能谱随角度的变化。
