【摘要】 在BaF₂中掺入1％mol的LaF₃结晶出BaF₂（La）晶体,经测试,此晶体闪烁发光快成份的强度比纯BaF₂晶体不减弱,而发光慢成份被抑制约4倍,耐辐照能力可以达到10⁶rad,表明新晶体有希望满足未来高能物理实验的要求。更多还原

【Abstract】 BaF₂（La） crystal has been grown with 1% mole of LaF₃ doped in BaF₂ and the scintil-lation properties of the new crystal have been investigated before and after a γ irradiation of⁶⁰Co source. The radiation resistance of the domestic crystal can be up to a dose of 10⁶ rad.Comparing with a pure BaF₂ scintillator, it was found that the fast component of the BaF₂（La）scintillator was almost no change but its slow component was suppressed to a factor of 4.更多还原
