A brief review of light dark matter particles and their spectroscopy ispresented, specifically aimed at understanding the interaction mechanisms ofaxion and Axion-Like Particles (ALPs) with matter and an interim proposal andsome ideas for possible detection of these evasive particles. In order toventure into the highly challenging spectral regions and extremely weak signalsinvolved with these searches (especially for the DFSZ axions), a differentscheme is proposed departing from the conventional resonant cavity mass scanand heterodyne detection methods. We aim to look for a fixed mass axionic fieldand concentrate our search at the corresponding resonant frequency and itshigher harmonics using a simple phase-sensitive dc detection method, whichcould possibly be helpful in substantially reducing both the hardware,experiment complexities and long run times. The probable mass range suggestedin the model presented here begins with 22.5microeV, corresponding to aresonant frequency of 5.4GHz, going all the way to its two multiples of 90 and112.5microeV (corresponding to 24.3 and 27.0GHz frequencies, respectively),with high probability of finding an axion or ALP around these mass values. Wepresent a comprehensive measurement strategy and spectroscopy technique basedupon this model which revolves around a three-stage amplification andphase-sensitive detection scheme to maximize and detect a resonant axioniccoupling to the U(1) fields under a coherent Primakoff effect interaction. Thefeasibility of proposed scheme is demonstrated with some calculations,simulations and preliminary tests. This experimental technique and ideasreported here have significant potential to be developed into an extremelysensitive narrow-range dark matter axion/ALP spectroscopy experiment.
