计算了玻色凝聚中赝标量粒子自激发射光子对的速率。随着密度的增长，该速率超过了正电子气体在合理密度值下自发双光子衰变的密度无关速率，从而在原则上为湮灭伽马射线激光的实现开辟了道路。
The rate of self-stimulated emission of photon pairs by pseudoscalar particles from Bose condensate is calculated. Growing with density, this rate exceeds the density-independent rate of spontaneous two-photon decay at plausible density values of positronium gas, thus opening, in principle, the way to the annihilation gamma ray laser realization.
