Abstract

This paper describes the experimental application of long single pulses to strongly inhomogeneously broadened NQR spectral lines, where the pulse length significantly exceeds the transverse relaxation time. A63Cu NQR resonance in the mineral covellite (CuS) was used as an exemplar for study in this specific regime, which was motivated by the requirement to obtain useful signals in very large volume applications having radiofrequency power limitations. In this study, signal transients that followed the application of the long single pulses were measured over a large range of radiofrequency field strength and pulse width. The results indicate effective generation of signal amplitudes. This is in contrast to previously reported studies involving long pulses applied to relatively narrow resonances. The results are found to be well described by simulations of the modified Bloch equations.

宽共振线的长单脉冲NQR
本文描述了长单脉冲在强非均匀加宽NQR谱线上的实验应用,其中脉冲长度明显超过横向弛豫时间。该研究以矿物钴岩中A63Cu NQR共振为例进行了研究,其动机是在具有射频功率限制的非常大体积应用中获得有用信号的需求。在本研究中,在较大范围的射频场强和脉冲宽度范围内测量了长单脉冲应用后的信号瞬态。结果表明,有效地产生了信号幅度。这与先前报道的涉及将长脉冲应用于相对较窄共振的研究形成对比。对修正后的布洛赫方程进行了仿真,结果得到了很好的描述。
